Reddit mentions: The best 3d printer parts & accessories

Most of these are less about upgrading, and more about fixing possible issues. But all of these are great to have and extremely cheap.


As others have said the glass bed and yellow bed springs are great, just be aware the amazon listing on there I used was shipped from china and took almost a month to show up. So pay attention to the shipping times.


The couplers the E3 comes with are straight up garbage. If they are not causing problems yet... they will. These are way better and give you plenty of extras if you ever need them:

​

The PTFE tube it comes with is also not great, any replacement one is usually better, and like others said with Capricorn you can print higher temps, but they also are manufactured to tighter tolerances and have less slack in your system. As to if this is a noticeable difference, it's arguable, but upgrading has fixed problems for some people.

​

Even more important than the tubing it self is the cutter you use, if you buy different tubing, make sure you get a good cutter so the ends don't get pinched. This can cause drag that causes underextrusion.

​

The plastic extruder on the E3 is know to wear out after a few months for some. A filament guide will help but a better aluminum extruder should fix it for good. They are cheap and easy to install:

https://smile.amazon.com/HICTOP-Upgraded-Replacement-Aluminum-Extruder/dp/B0761PGLZ4/ref=sr_1_1_sspa?keywords=ender+3+extruder&qid=1558892498&s=gateway&sr=8-1-spons&psc=1

​

Once you want to go deeper down the hole, the two big mods that you will be happy with are A auto bed leveler and quieter stepper motors. There are guides for both of these on youtube and they are much more complicated and a bit more expensive but give amazing results.

​

A BLTouch goes for about $80 with the extension cable so you don't have to cut wires. It will make it so you save an offset and basically rarely have to level your bed again and the machine will account for most of it. There is another type of leveler I think it's called EZABL or something like that, but I liked the BLTouch option better so I never did the research on it.


If you want to do more upgrades like a touch screen, filament rounout sensor, and etc. you need a different main board. Most people upgrade to the MKS Gen L. They are about $25 bucks but require you to also buy new stepper motor drivers, which i'll touch on next. The board has more memory and slots for upgrades that the stock board does not. It does require a lot more setup and printing a new housing for the board. Again there are great youtube videos, just search for 'Ender 3 MKS Gen L'

​

If you think the Ender 3 is loud and would like it to be WAY quieter you can install better stepper motor drivers. The TMC 2208 driver will make the movement almost silent. you will still hear the fans, but the movement sound will completely gone. To install them you will need to either use the above mentioned board (as the stock board has the drivers integrated) or if you want an easier way you can order the Ender 3 Silent Ver 1.4 board:

https://www.creality3donline.com/creality3d-new-upgrade-silent-114-mainboard-for-ender-3-pro-ender-5-customized-und-non-standard-matching_p0147.html

This won't give you the upgradabiliity of the MKS board, but is a direct drop in replacement that gives you the silent steppers.

​

Welcome to family, and I hope some of that was helpful

> Thanks in advance for answering my questions.

• How long have you had your Flashforge, and how much have you printed on it?
  
  I purchased it last August. (781 hours logged) It's almost litterly been printing out of the box since day one. The only issue I had out of the box is that the one screw on the build plate got bent as a result of the 2 free spools bouncing into it. I ordered a box of them from McMaster and had it fixed by the end of the week. I contacted Lisa on their google chat form and from what I understand, they now come with the screw as a result of my support ticket. This was an annoyance yes, but I've had more issues with my reprap and that costed me more than this pritner when I bought it. (I originally had a Makergear Prusa)
  
  
• What do you like the most and the least about this printer?
  
  Most: I love the fact that it prints 100% of the times I try to print something. I rarely, and I mean RARELY have a failed print. I love that I can hit print before I go to bed and wake up to a completed part in the morning.
  
  Least: This is small, and it took a while but I have since out grown the build platform (9x6x6 inches). I recently ordred an 8x12 plate from McMaster and that arrives on monday and we'll see how that works. (PSA this requires removing one of the extruders - if you want more info on this let me know)
  
  
• Have you printed with ABS?
  
  Yes, no issues. Just close up the printer with the included panels.
  
  
• If so, did you experience any problems such as curling?
  
  No, I use a glass build plate and a thin coat of purple glue stick. I then spritz water on the plate before each print. I never have a sticking issue and I never have warpage. I personally prefer PLA though since Hatchbox has come to light and makes GREAT PLA
  
  
• Have you had any problems with the metal bed warping or with leveling the bed?
  
  Like I said just above, I use a glass build plate, so I haven't had any warpage issues with the bp. Leveling the bed is a bit of a challenge but I'm fussy about it and I want it within 0.0005 or less so it takes me a while. The reason I'm fussy is because I've only had to level the bed 2 or 3 times since owning it.
  
  The first was when I got it
  
  The second was when I added the glass build plate
  
  The third was when I removed one extruder and added an aluminum carriage.
  
  That's it. It never lost it's level and it's gone through 3 moves (like I moved apartment to apartment)
  
  
• Finally, how is the customer service or community support for this printer? Thanks again!
  
  The only experience I had was with that screw initially. I contacted Lisa on their Google Chat forum and she handled it mostly. Sadly, it wasn't as 'perfect' as I wanted since their solution was to send the printer back instead of sending me a new screw. Never the less, they did try to help on the matter and told me how I could go about getting money for the screw if I so desired. In the long run, it's a screw and I just ordered them from McMaster. I have zero regrets from it and I think I know my printer a bit beter because of it.
  
  single extruder carriage (PSA: their single extruder block is not FF compatible.
  
  My Thingiverse for example prints
  
  Some things I would buy shortly after getting the printer:
  
  Spare Extruder fan : I tend to slip and put a screw drive in the path of this, shattering the blades. If you're a clutz like me, get it. I've needed 4 so far. ::hangs head in shame::
  
  Glass Build Plate : Best purchase I've made for my FF. Works great, easy to install and use. Also get thermal sheets and purple elmers glue, and print the spacer found on my Thingiverse page under "Flashforge Upgrades". Also get a spatula, and dikes
  
  Simplify3D : A lot people tend to spend $X,XXX on a printer and then try to use free software with it and complain when it doesn't print right. To me that's like buying a car without tires. A Corvette ain't shit without a decent set of tires. It's kind of pricy compared to free, I know, but at real CAM programs (which is what this basically is) cost $8,000 or more. It truely is a great printer program and I wish I had purchased it much MUCH sooner than I had.
  
  Last and most importantly, get the an active cooling fan. I originally printed this, and purchased a 12v power supply and added some fans to it. I have since moved on to the offical one from FF. It's not as good but I haven't really ran into an issue. If I had to print from my right extruder, it would be an issue though. What I liked about it, is that it's a plug and play added on. No "modifications" needed to added.
  
  TL;DR / Closing thoughts: I would buy this printer again in a heartbeat. ESPECIALLY if they came out with one similar to the Replicator 2 with the 11.9" build plate. Instead it looks like they went a different way judging by CES but oh well, there's always next year. Further more, I think this is a great entry level printer for someone looking to have a printer help with projects and not be one of them. That doesn't mean you can't mod it or upgrade or whatever, it just means you don't have to if you don't want to.
  
  
  Hope this helps and answers any questions you might have. Feel free to ask more though!
  

I've owned the Ender 3 for a few months now and have made a number of upgrades, both purchased and printed. Here's a list of what I have purchased and printed, sorted by importance/usefulness.

 

Purchased Parts:

1. EZABL - An automatic bed leveling solution that has worked really well for me. TH3D's firmware and documentation are top notch. Once I dialed it in I've had no issues with bed leveling or adhesion. Also note, TH3D is an American company and Tim, the owner, is even a mod of this sub!
   
   
2. Stepper Motor Dampers - A great way to quiet down the printer. My bedroom and office are connected without an intervening door and the dampers allow me to print overnight and still get get to sleep. Some users have had issues with stepper motors running hot with the dampers installed, but I've had no trouble at all, even after 16+ hr prints.
   
   
3. 5015 Blower Fan - For use with the Petsfang Duct, see below.
   
   
   
4. Assorted M3 Screws - If you're going to be making mods to your printer, you're eventually going to need different sized screws. Having various lengths on hand is super helpful when trying to mount a new part.
   
    
   
   Printed Parts:
   
   
5. Filament Guide Arm - This has helped a lot with keeping the filament feeding smooth and preventing under-extrusion issues. There is a more popular model on thingiverse, but I found this version to be stronger and more stable.
   
   
6. Petsfang Cooling Fan Duct - An extremely popular replacement for the part cooling duct and fan. This creates much more even cooling around the filament as its extruded, providing better bridging and better overall print quality. There is a version using a replacement 5015 blower fan, as I have used, and there's a version called the "Bullseye" that uses the stock fan. I chose to replace the stock fan because mine was starting to rattle.
   
   
7. Tool Holder - It sounds frivolous, but having the tools you need right at hand can be a big help in saving a print or performing trouble shooting. Definitely a must have.
   
   
8. LCD Rear Cover - Protects the circuit board behind the LCD, which is exposed from the factory. If you have children like I do, this is a must.
   
   
9. Cable Chain - Routs the various cables to their destinations in a clean way. Looks super cool. Not necessary, but definitely fun. Note, there is an X-axis cable chain setup available, but I found it made excessive noise and wasn't worth the trouble.
   
   
10. Fan Shroud - Protects the main board fan from bits of filament falling down into the casing.
    
    
11. Storage Drawer - A handy little drawer that slides in next to the LCD. I store things like alcohol swabs, razor blades, and other random tools in it.
    
     
    
    Future Upgrades:
    
    Spool Roller - One issue I've found is that the stock spool holder requires excessive force from the extruder to unwind filament. A replacement spool roller with bearings should reduce the friction significantly and produce more even extrusion.
    
    Metal Extruder - A common problem with the Ender 3 is that it fails to maintain proper tension on the extruder gear, which leads to failure to feed and poor extrusion. An all-metal extruder has been known to fix the issue.
    
    
    
    
    
    

I have a Maker select. It's my first and only 3D printer so my review compared to others is unreliable.

Here's a copy/paste of a review I did on it about a month ago. It's long but detailed with links:

I will give you my background before my opinions. As everyone has different goals, opinions, and experiences.

I got my printer near the end March of this year. I have something like 2500m of filament run though it, and no idea how much print time.

When I received my printer, my test prints failed and I was pissed. But this community helped improve my Cura settings and started producing usable parts. I then went nuts and printed out a BUNCH of mods. This is by far my most favorite thing. There's always something I can print to improve the quality of the prints.

THe down side is I went too far and got to a point where I couldn't produce anything of quality. So, 2 weeks of tweeking and researching later I'm printing in PETG with beautiful quality and very minimal visible layers.

My most recent project in PETG:
http://i.imgur.com/sVf7S2D.jpg?1

So, now to answer your question...

> How do you like your Maker Select?

I love it. It allowed me to buy a cheaper printer (One of the cheapest at the time @ $350) that produced amazing results. It also has upgrades you can purchase or print to improve the quality, so investing smaller amounts over time to make it better and better. I highly recommend it to anyone who is starting because it does require tweaking which forces you to learn and understand how exactly 3d printers work. A major plus was that this community has a lot of Maker Select users for support, which was a MAJOR plus for me.


As of today, I've purchased the following upgrades:

• IKEA enclosure - $115
  
• LEDs for Inside enclosure - $25
  
• MK-9/10 Extruder Gear - $9
  
• Micro Swiss All Metal hot End - $50
  
• Micro Swiss Lever - $18 (Totally not necessary, but Micro Swiss's support was AMAZING to deal with, and I wanted to support them so I purchased this as well.
  
• Misc. M3 and M4 Screws, etc. - ~$25 in total between Amazon Orders and Lowe's for things needed for mods.
  
• New 40mm fan because I broke the blade on the one I had. There are cheaper ones than this. - $14
  
• 50mm blower fan - $8
  
  So, in the last ~3 months I've spent an additional $264... Oh god, don't tell my wife! All are totally not necessary, mind you. The only thing I'd 100% recommend you do are print out the following to mods:
  
  DiiiCooler along with buying the 50mm blower fan. There are cheaper options out there, I just wanted it faster so I bought it through Amazon to get free 2 day shipping.
  
  z-Brace - This is key, and will run you maybe $15 worst case scenario to get enough M4 screws and the threaded rods.
  
  Edit: Forgot a couple more things I bought.
  
  
• Lowe's glass - $4 for 2 pieces of 7.9"x7.9" glass
  
• Borosilicate Glass - $12 - Amazing adheasing with PLA and ABS. Don't use it right now, though because I'm printing in PETG and I read on here that PETG eats borosilicate glass.
  
• Lithium Grease - $7. When I changed my bearing blocks, I had issues with sticking so I purchased some of this to help smoothing out the bearing movement on the polished rods.
  
• 3D print removal tool - $5. Printer comes with a larger scraper, but I needed something a bit more fine (thin) and this thing is perfect.
  
• Spare bearings - $13 because I broke one of them when swapping to 3d Printed bearing blocks.
  
• Digital Calipers - $18
  
  That's another $59, so $323... I have a problem. again, 95% of this is NOT NECESSARY. I'm just addicted to modding.
  
  

I got my Ender 3 Pro about a month ago, performed some upgrades and ran into a few problems, but with some weird caveates.



I'm trying to print multiple miniatures on a single print, but seem to be getting a lot of oozing or stringing issues, but when I test with retraction tests, the test comes out perfect with identical settings. Additionally, when googling around, I couldn't find anything except for potentially a nozzle clog or potentially hydrated filament (possible, I'll test this later)

​

I've tested a few other prints as well, a benchy and a testcube, they print fine. Really curious about what's going on. Do I need to spread the prints out more, use different settings, or is it more of a mechanical issue?

​

I'd appreciate any help you guys have to recommend!

​

So, lets get down to it:

Printer: Creality Ender 3 Pro

Surface: Creality Glass surface

Upgrades: Aluminum extruder upgrade

Capricorn Tubing

New bed springs



In addition to these, I've tightened the X and Y bolts on the runners to reduce wobble -- there's no more wobble, maybe they're too tight? I don't think so, I've had good prints with these settings, but not with a few things.



Settings:

Basically the same as the "normal" settings for the Ender 3 on Cura 4.0.0

But in addition: (And what I think may be important is bolded)

adhesion_type = raft

layer_height = 0.12

support_tree_enable = True

support_type = buildplate

brim_outside_only = False

fill_outline_gaps = True

infill_pattern = cubic

infill_sparse_density = 25

material_final_print_temperature = 180

material_initial_print_temperature = 180

material_print_temperature = 185

optimize_wall_printing_order = True

raft_margin = 10

retraction_amount = 7.5

retraction_speed = 20

speed_print = 30

support_angle = 40

support_conical_enabled = True

support_infill_rate = 50

support_interface_enable = True

support_pattern = lines

** NOTE ** Standard supports are turned off, I'm using the tree supports

support_tree_collision_resolution = 0.15

travel_avoid_supports = True

travel_compensate_overlapping_walls_enabled = False

wall_thickness = 1.2

First of all, you're going to want to update the firmware in the controller board. Creality has a history of shipping printers with older versions of Marlin that lack thermal runaway protection, which is kind of important if you value your home being not on fire. They may have already fixed this, but it's certainly something you'll want to check.

Here's a tutorial:

• Part 1 https://www.google.com/amp/s/m.all3dp.com/2/ender-3-with-marlin-how-to-install-marlin-firmware-on-your-ender-3/
  
• Part 2 https://toms3d.org/2018/09/17/update-your-3d-printer-firmware-without-a-bootloader/
  
  And here's the cheap programming adapter I used to complete the update:
  https://www.amazon.com/gp/aw/d/B01IBFMJEA?psc=1&ref=ppx_pop_mob_b_asin_title
  
  Beyond that, I printed a few upgrades for the printer itself.
  
  A fan guard to keep scrap filament from the bed from falling into the controller fan. https://www.thingiverse.com/thing:2935204
  
  A surprisingly useful tool tray to keep the various tools neat and contained https://www.thingiverse.com/thing:2883898
  
  Some cable chains mostly for cable management aesthetics but also to prevent damage to cabling during use https://www.thingiverse.com/thing:2920060
  
  A filament guide https://www.thingiverse.com/thing:2917932
  
  Some retaining clips to keep the Teflon tube from moving around during retractions: https://www.thingiverse.com/thing:2845931
  
  There are also tons of part cooling fan ducts to play with in order to get cleaner overhangs at various angles.
  
  It's also commonly advised to upgrade to stiffer bed springs to avoid having to relevel the bed as often, but I haven't had an issue on this front yet.
  
  Another common idea is to print on glass. But my bed came flat from the factory and I've been enjoying printing on the flexible removable build surface. And a pane of glass is more mass to sling around which may potentially cause ghosting. But if your bed does come warped, you'll want to run to the hardware store and get a few cut.
  
  I upgraded the Teflon tube to one made by Capricorn. I haven't noticed any difference in print quality, but they advertise that their special Teflon blend has better temperature Resistance which, in the absence of the all metal hotend, adds a wider safety margin for higher printing temperatures.
  
  But by far, the best upgrade was to put some cardboard shims underneath the feet of the printer. This dramatically reduced the amount of noise made by the printer.
  
  Also, if you want to upgrade to printing Zytel, you'll need an all metal hotend like this one: https://www.amazon.com/Micro-Hotend-Creality-Printers-TronXY/dp/B0789V2D7C/ref=mp_s_a_1_1_sspa?crid=D0IRZSZQ80PZ&keywords=ender+3+micro+swiss+hotend&qid=1556175003&s=gateway&sprefix=Ender+3+micr&sr=8-1-spons&psc=1
  
  Hope this helps!

Best thing to do is get some Mirror Tiles at any Home Improvement store. Cheap and flat (who wants a wavy mirror? LOL).

Lowes in the US has them $9 for Six. I had two not flat but 4 fine. Home Depot and Ace Hardware also have them IKEA is another source.

>Athorbot adhesive mats - Those are a knockoff clone of the BuildTak mats. They're OK, but do wear out.

I went down that road last year, ended up using PEI on my printers and haven't looked back:

https://smile.amazon.com/gp/product/B074XLD5QH

Sticks well when warm or hot, releases almost instantly when cool.

But BEFORE any of this works your Bed needs to be flat,most machines it's NOT. (Not the glass, the Aluminium bed).

A quick check with a known straight edge (like a 24" machinist's rule) will let you see. Put it edge on with a well lit white wall or sheet of paper and check the bed, front to rear, also side to side.

Most have a dip in the center, some are raised in the center.

Unless the glass is VERY thick, it will dip when clipped to the bed.

I did a couple posts / comments about how to properly flatten the bed. It's a bit of work, but you'll do your happy dance when it's nice & flat.

Most adhesion & first layer issues are caused by an unflat and un-trammed (proper name for "leveled") bed. Probably 50-60% of the "Help Me!" posts are this!

With a properly trammed bed you don't need glue or Hairspray, or tape or other "goop" in 90% of the cases. You can actually print straight onto the glass or PEI, many do. (including MOI) Super smooth bottoms.

Here's' the posts, first, some basics:

https://www.reddit.com/r/CR10/comments/86c47m/psa_a_must_read_by_anyone_who_levels_their_bed_or/

Then follow this to tram the bed:

https://www.reddit.com/r/CR10/comments/7rpq2x/can_i_simulate_a_print_without_damaging_the/

Let us know how it goes!! Trust me, it's worth the effort.

Congrats and welcome to the club!

> Some of the supports looked "wonky" during the print. Like, they didn't go "straight up". Is that normal or did it not have enough cooling?

Not sure what you mean. This print doesn't use supports. Do you mean the walls? Any photos that can show us what you observed?

When printing PLA, more cooling is almost always better: hard to have too much. I'm not sure what problem you observed or whether cooling would have solved it, but better cooling will definitely improve future prints.

> As you can see, it was printed on a raft. If you look cloesly, the bottom of the of the butterfly has a slight lip around it (like the first couple layers are wider than the rest. Is there anything I can do to improve upon that so it's straight the whole way up and down?

Hm, it's not as common to see elephant's foot for something printed on a raft. Usually it happens from the nozzle really squishing the first layer into the bed, or the bed being too hot.

You'll want to learn how to print without rafts ASAP, at which point you'll want to keep an eye on that. Leveling and temperature will make a difference once you're printing directly on the bed, but the best solution is usually a model that compensates for this with a chamfer. After all, really squishing that first layer helps with adhesion and finish. A chamfer allows this without the elephant's foot.

> It has a heated bed with that "sticker/tape/thing".. Does that mean I don't need to bother with painter's tape/a glue stick/hair spray?

I just print straight to my Maker Select bed (with their version of Buildtak that you show in your photos).

Some people still add tape/glue on top of it, but I haven't found it necessary. I've printed everything straight on the bed (mostly PLA, some PETG and TPU) and haven't had a problem yet with adhesion (knock on wood).

> I plan on doing the MOFSET mod and getting a glass plate as soon as I replenish my "fun" funds next month (kinda drained it all picking this thing up).

Just my opinion - some others will disagree - but I'd put money towards the MOSFET before new filament. Maybe you don't have some of the tools and would need to buy them, but the MOSFET itself is just over $10. That's less than a roll of filament and protects the integrity of your new purchase.

I'm pretty new to this too, I bought my Ender 3 Pro around the same time as you. Quiet printing is pretty high on my list as well as being able to print high-temp exotic filaments in the long term while maintaining reliability.

First upgrades I purchased were stiffer bed springs so I would be less likely to throw the bed out of level while removing prints or working around the printer and Capricorn XS tube since it has a more consistent internal diameter, fits closer to the filament, and can work with slightly higher temps. I also picked up a pack of bowden couplers recently as I noticed the end nearest the extruder is sliding past the coupler jaws on de/retraction; don't worry about that unless it's an issue for you. That's about $30 alone since I don't have a supply shop locally and have to order those parts in bulk. I had a Pi 3B laying around unused and flashed Octoprint onto it. Highly recommended. I have a replacement Noctua hotend fan, buck converters, and 5015 blower on order to quiet the fan noise; about $32. Just replaced the Meanwell psu fan with a 60x25mm Noctua I had lying around (Note: there may be better options in the 92-120mm range to replace part of the PSU housing, but that's what I had laying around). Next upgrade coming is the SKR Mini E3 with TMC 2209 drivers ($28) to eliminate almost all of the stepper noise. Also looking into a replacement for the control board fan and some vibration isolating feet for the frame. As far as higher temp printing I haven't made a lot of progress aside from buying a titanium all-metal heat brake ($11) winch I have yet to install or inspect, and looking into enclosure and electronics relocation avenues.

Either way the mods I purchased came in at around $100 US which should quiet the printer and help with reliability. Also looking into picking up a good M3-M4 bolt kit if any exist in the US.

upgraded carriage plate, should be one of the first things you do, the stock one is flimsy and prone to warping, making the print bed extremely hard to level reliably.

https://www.amazon.com/Micro-Hotend-SLOTTED-Cooling-Wanhao/dp/B01E1HANLS/ref=sr_1_fkmr3_1?ie=UTF8&qid=1497736485&sr=8-1-fkmr3&keywords=i3+plus+all+metal+hotend

all metal hotend will enable you to print at much higher temp, and increase reliability of the print head. not strictly needed, but a great upgrade if you want to print abs, petg, or other higher temp filaments.

https://www.amazon.com/dp/B01HCVJ3K2/ref=sxr_rr_xsim_1?pf_rd_m=ATVPDKIKX0DER&pf_rd_p=3008523062&pd_rd_wg=sUxZ5&pf_rd_r=W5Q7RV181EJYGTBW4YDJ&pf_rd_s=desktop-rhs-carousels&pf_rd_t=301&pd_rd_i=B01HCVJ3K2&pd_rd_w=ZPXZq&pf_rd_i=tri+gorilla&pd_rd_r=F2X8G4XDPCVTNXX6J560&ie=UTF8&qid=1497736655&sr=1

heater bed mosfet upgrade. again, not strictly needed, but also useful for high temp filaments like abs, as you can run the heated bed at higher temps. also solves (small possibility, i3 plus supposedly fixed issue) of stock mosfet burning out and catching fire.

https://www.thingiverse.com/search?q=i3+plus+cooler&sa=&dwh=295945a7ab3d0cd

print a cooling fan shroud, i use the ciiicooler, the diiicooler is great as well. preferably in abs. BIG quality improvement, the stock fan is useless.

these are some of the ones i use, and there's a lot of other things you can do, extruder gear, improved bearings, too many to count really, just a matter of how far you want to go for incremental gains. the carriage plate and the cooling fan shroud are the only strictly necessary ones though.

oh and i made my own version of this z-brace, don't have the files anymore unfortunately, but this one is fine:

https://www.thingiverse.com/thing:1653631

that's also something you should do asap.

Thanks for making a new thread. You mentioned pre-assembled and quality/reliability over cost, but do you have a general price in mind?

Extruder

The most popular option is to just go with one of the cheap aluminum extruders. These are a considerable improvement over the stock plastic version. There isn't really much assembly involved, you will need to bolt on the extruder plate/lever and put the spring in, but it's about the most simple upgrade there is.

On the more premium end, depending on which version you buy, a genuine Bondtech comes pre-assembled. It's about $70 more expensive and the benefits are negligible, but that's an alternative.

Hotend

The two main choices for Creality machines are the V6 or Micro Swiss (or a clone), both of which do have some assembly involved.

E3D sells their V6 as a bunch of parts that you assemble yourself, but Filastruder offers it as a pre-assembled version. I believe most V6 clones come loosely pre-assembled as well. Keep in mind however that V6 isn't a direct install, you will need some kind of printed bracket / fan duct like the PetsFang to mount it.

The Micro Swiss on the other hand is a drop-in installation on Creality machines. You do have minimal assembly putting a few parts together, but it bolts up to the stock machine without any changes. I wrote a guide that covers how to do it for the Ender-3, but the Ender-5 uses the same hotend carriage design, meaning the steps are the same.

---

I would personally go with the cheap aluminum extruder and a Micro Swiss hotend. This would be a cost efficient, yet effective set of upgrades for the machine. There is minimal assembly involved, but there isn't much on the market that is 100% ready to go.

Hey! Welcome. I also just bought my ender 3 pro as my first printer.

​

Here's a great place to start https://all3dp.com/1/20-must-creality-ender-3-upgrades-mods/

​

​

So far I've done the following upgrades:

1: Metal Extruder. 100% necessary and MUCH easier to do during initial assembly rather than an upgrade. I got mine form Amazon.

https://www.amazon.com/gp/product/B07J44QW8B/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

​

2. 2020 Filament Guide:

You can find this on Thingiverse and is about a hour long print. It actually made a noticeable different in some salmon skin issues I had in my first couple of prints.

​

3. Springs:

These just arrived today so I'm not sure how much they will help but one of the main causes of my failed prints so far as been issues with leveling and some of the stock springs I can see are just no good.

​

4. TL Smoother:

Another upgrade I havent had a chance to set up yet. That said, my research has come across mixed results. Some people love them and some people Hate them.

​

I'm not sure about glass beds and all, the stock plate has been working pretty well for me. I think I'm going to try it alittle more before moving to a glass bed simply cause its a bit easier to maintain but it could be the next thing on my list. I've also been considering an auto-leveler (and ardunio) since it doesn't have that function and having to relevel, watch, pray, reset has already cost me a couple hours of print time.

​

I'm not familiar with ESUN PLA+, I've been using https://www.amazon.com/gp/product/B00J0GMMP6/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

and am very happy with it so far.

​

Best of luck with your printing!!

My MS is out of commission right now due to a motherboard issue - but that's not something that's common occurence with these machines. That aside - I love my MS, it's a damn good printer for the price and works really well. Plus it's on the cheaper side of things and can be upgraded pretty easily. I would suggest getting this printer, and a glass sheet for a bed upgrade. The buildtak stuff they put on it is fine for a little bit, but the glass just produces better results in my experience. And if you want to at a later point in time, a MK10 all metal hotend nozzle upgrade (with cooling block) is also a fairly cheap and easy buy/install. Just the core machine though, no mods - is really good and easy to install and calibrate. Totally would buy another one if I could right now.

Glass bed

Nozzle upgrade

Seconding everything people have said here and want to add the following.
A glass bed with 10mil PEI from CS Hyde will do wonders for bed leveling.

Upgrade your Y plate as soon as possible, the stock one warps over enough time making bed leveling nearly impossible.

All metal hotend such as the micro swiss is amazing, no more clogged PTFE tubing, easier to clean if it does.

Z brace is a must, also print a fan cooler like the Diicooler on thingiverse. Replace the stock part cooling fan with a nice radial fan, plenty on amazon, make sure its 12v. This helps prints come out cleaner.

Yours should come with thumbwheels, if not, print some, bed leveling is easier with it.

Print some spring cups as well, keeps the springs straight and not bending when leveling the bed.

DO THE MOSFET MOD TO MAKE IT SAFE!

Watch this vid and do his printed mods https://www.youtube.com/watch?v=Tpcm4XEbP1Q&t=752s&list=PLyIdpN_zILcknsQzSZSiWhQ685NxkWsvD&index=2

Also, stay far far FAR away from Shaxon filament! It broke my hotend, check my post history to see the red glob of death I dealt with. I have had very good luck with eSun PLA.

Sorry I can't answer all of your questions, but here's a few suggestions. Number one, a better part cooling fan. Just buy a cheap blower fan like this one, and print a radial cooling fan like this one. This should help a bit with your bottom screw holes being messy. For bigger prints this is a necessity. When it comes to getting prints off of the beds, I use a glass bed with a gluestick for adherence, and to remove prints I use this thing. Incredibly, incredibly useful. It's thin enough to get under prints without denting them, and the long design lets you move it underneath prints to free the whole this. The end is also sharp enough to scrape glue off of the printbed. Works a lot better than the scraper included with the printer.

Not much really. The benefit of buying the mk2s is that you really don't need to modify or swap anything.


Here are a few things you might want in my opinion:

• You might want some different filaments. You can stick with the brands and types that Prusa includes printing profiles for, or for other brands and types you may have to do some testing to find the right print temperature, speed, cooling, etc. Reading up on that process is a good idea.
  
  
• A paint scraper can be helpful for removing prints from the print bed, just be careful not to scratch the print surface.
  
  
• Some rubbing alcohol. Rubbing alcohol or window cleaner is what Prusa recommends to clean the PEI print bed. You can also use rubbing alcohol for this very cool trick to help loosen stuck prints
  
  
• A good set of calipers can be handy for measuring printed objects, measuring real-world objects you're trying to model things to fit, etc.
  
  
• bookmark some fun things on Thingiverse, MyMiniFactory, etc. that you'd like to print. Especially some small things that you can print quickly in your first few days/weeks with your printer that don't require painting, other parts, etc.
  
  
• I found my printer printed much better after I calibrated the Extruder and the Z-height. A decent extruder calibration process for the Prusa can be found here. The same site has some info on calibrating z-height, or I had good luck with this method. Mine was a kit though, so it's possible those are pre-calibrated with the assembled printer.
  
  
• You can buy different size and different material nozzles for the e3d hotend. Hardened steel nozzles are recommended for most of the filaments that have stuff embedded in them (carbon fiber, wood, etc) as those are really abrasive on the standard brass nozzle and can deform it internally,, causing later printing problems.
  
  
• Paint, sealant or epoxy can be useful for finishing up models. I haven't tried it myself, but I've seen pictures of some awesome results using this epoxy to give a smooth, hardened finish to your prints. Standard acrylic hobby paints are also great for color and pizzazz to your finished prints, especially more artsy stuff.

What I did was I got a nice thick borosilicate glass plate from amazon, the one with the corners cut off so it fits the bed perfectly without the heated bed bolts interfering. Then I got a sheet of PEI with 3M adhesive on the back. I cleaned the glass with alcohol and then carefully applied the PEI so there weren't any air bubbles.

​

This is the glass:

https://smile.amazon.com/Gulfcoast-Robotics-Borosilicate-Duplicator-Printers/dp/B07B2YLWF9/ref=sr_1_5?crid=2640M0KDOPOV&keywords=borosilicate+glass+plate&qid=1555903635&s=gateway&sprefix=borosilicate+glass+pl%2Caps%2C153&sr=8-5

​

And this is the kind of PEI:

https://smile.amazon.com/Gizmo-Dorks-Preapplied-Laminated-Adhesive/dp/B07GSJSDWR/ref=sr_1_4?keywords=PEI+sheet&qid=1555903728&s=gateway&sr=8-4

​

I have gone through a handful of these borosilicate sheets, and have had one or two that were warped. All of them were thinner than the Gulf Coast Robotics one. Theirs is bang on flat and way tougher, hands down the best. When you apply the PEI, make sure you do it very carefully as to not create any bubbles underneath. I started on the center of one edge and slowly applied from one side to the other, peeling the backing off as I went. Press it down from the center out as you lay it down and you shouldn't get any bubbles. Lots of very tiny bubbles are to be expected and work their way out after a while (Im talking really tiny). As for attaching the glass to the bed, a set of four binder clips are perfect. Don't bother with the thermal pads some people suggest, they make it a pain to remove the glass in between prints and don't really do anything.

​

This is a great way to have a removable build surface that everything sticks to. I have since moved up to a Prusa MK3, so I get to enjoy the luxury of the magnetic PEI build plate. You could get a similar thing going, BuildTak sells a magnetic build surface that you apply to the heated bed. The drawback of this is that if your bed is warped at all, the magnetic sheet does nothing to correct it. The thick glass on the other hand makes everything nice and flat.

​

I should add that to put the glass sheet on, you will have to move your z endstop switch down. There are several mounting holes on the printer to do this already so its really not that hard, you just have to experiment. The glass is about 4mm thick so you have to adjust for it.

Wow, thanks for going though that!

Though I'm going with the advice that almost everyone is saying on this post and wait for the printer to arrive.

That said, I'm going to buy the dampeners anyway because I'm in an apartment that the walls are thinner than most apartments in my area. I know that it's a 3-5 db difference based on what I read, but the lower the sound, the better.

I'm going with these dampeners

​

I'm also going to get the M3 Scews anyway as well just to have spares.

> My glass was warped. I used the tape it came with to flatten it but then got the mirror.

if the glass bed is warped when it arrives, I'll get a mirror tile after making sure that the printer is working fine.

> Mine came with large knobs already. And the print bed strain relief for the wires.

I've been told now that this is the case. Though I did buy this from the GearBest US Warehouse so I don't know if what they have is the latest. though I guess I'll find out on Thursday.

> I'm still using the stock clips. Or you could print new ones.

I wasn't aware that stock came with clips! So I'm going to skip getting clips until the printer arrives.

> Maybe. I've been using a mirror from Home Depot and it's been ok. I saw the creality magnetic mounted surface was only $22 on amazon so I actually ordered that today.

Can you let me know how that goes? I was wondering about those too.

> Mine came with the upgraded extruder that works better with TPU and such. The holes already started wearing larger though where the filament fed so I got a $20 aluminum setup.

did you order those upgrades or are they on the printer?

> I'm using this new hot end vent ring too this week and been liking it. https://www.thingiverse.com/thing:2912394

Dumb question but are you using PLA or ABS for that vent ring? Just curious.

​

Thank you so much for the advice!

8 bit boards are the reason prints are slow. They just can't calculate fast enough for precision. Some new affordable 32 bit boards are finally starting to show up. I'm guessing Prusa will design his own 32bit board.

​

Maybe a custom E3D hotend that can produce enough heat to keep up with faster print speeds.

​

I think a more polished way of doing the nylock mod will be part of the printer. I'm quite happy with the process of the nylock mod now in conjunction with the plugin that helps with the process big time.

​

I'd love to see a larger print volume at the very least in the z axis. I swapped the smooth rod bearings out for these and that took an already quiet quiet printer to a whole new level of quiet and NO MORE OIL. They are impregnated with lubricant.

​

I'd LOVE to see a better way to mount the whole extruder assembly to the z axis rails. You can over tighten the screws and put too much tension on the bearings (both my new ones and the stock metal ones) and restrict movement enough cause homing issues. I do my best not to ever over tighten certain screws and it still happens once in a while. I've gotten used to it but a better way to mount it would be appreciated.

​

Maybe a few built in LEDs around the hotend and even a more visible nozzle end. Have the fan duct on the back side or something.

​

One last thing would be a better main board housing that better handles the cables going into the bod. Maybe two entry points so securing the cables going into the box isn't so extremely tight fitting.

​

Ok, one last last thing. No more tiny pieces/tiny 'appendages' on large parts that can easily break off. I know that may not be possible but why not mention it.

How quickly were you printing your pieces? Some of the parts I saw in your album looked a bit on the rough side (overhangs, perhaps?). Meaning no disrespect of course, I think your projects are awesome! I have a Maker Select and I can get some really nice quality prints without going excruciatingly slow, so I was just curious.

Can I ask what mods you have on your printers? I saw one of them has the support braces, but have you experimented at all with other things? If so, how did they effect your prints?

The only mods I have done are installing an all metal hotend and printing off a new vent for the front fan. I used this one in particular (with a 40mm fan). The hotend mod on it's own significantly improved my print quality, and the vent made printing more intense overhangs a lot less messy.

Either way, those are some great builds! I love the look of the laser rifle. :)

I'm not sure how much help I'll be, but I also use a Flashforge Creator Pro...

1: If you're sick of dealing with abs, just put some blue painters tape on the bed and print PLA, once you open up the thing enough and modify your settings it does PLA perfectly well.

2: PVA glue stick, (though it looks like you are already using this) helps with bed adhesion with ABS and also gives you a bit of an ablative layer for when you are scraping things back off.

3: get a print removal tool like https://smile.amazon.com/ToyBuilder-Labs-Print-Removal-Tool/dp/B00VB1U886/ref=sr_1_4?ie=UTF8&qid=1494526580&sr=8-4&keywords=print+removal+tool to help pry things off the bed without destroying the sheet.

4: rafts, these really help with getting things off the bed, you waste quite a bit of plastic, but it's much easier to get things off.

5: bed level (and height) adjustment (and this really should be number 1) the little plastic sheet they give you to slide under the nozzle is of no real value, you may just be printing the first layer way too close to the bed, and absolutely squishing the filament into the bed. It is far more useful to just print a leveling pattern and then see where the bed needs adjustment and how it's extruding than to even bother with pulling the sheet out from under the head. I use this one http://www.thingiverse.com/thing:97151 and generally will tweak things until the strands are attached but will come off with my fingernails.

I'm at 2,000 meters of filament printed with my Maker Select, very happy with it, some tips:

-The Maker Select V2.1 is simply a re-brand and upgrade of the Wanhao Duplicator i3. You'll see that name "i3" thrown around more than Maker select, so just be aware they are nearly synonymous


-First, definitely get the blower fan upgrade: https://www.amazon.com/gp/product/B00MJU6JR2/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
Buy two of them to have an extra in case of death


-Print out a blower fan housing for that fan: http://www.thingiverse.com/thing:1025471


The fan upgrade provides a huge improvement in print quality


-Get the all metal hot end from micro swiss: https://www.amazon.com/Hotend-Nozzle-WANHAO-FlashForge-Builder/dp/B01C3HEQZC


-THe "Z-Brace" mod reduces vibrations from the machines movements: http://www.thingiverse.com/thing:921948


Some people swear by it, but the print time for those parts is roughly 20-24 hours total. In my 2,000+ meters of print, I haven't bothered because of the print time, but still bought the extra pieces in case I decide to do it.


-I've been mass printing tiles for d&d too, I looked at openforge and decided against that line, but went with TrueTiles instead. https://www.youtube.com/watch?v=JUecWG1W-ss


Highly recommend truetiles over the other tile lines out there - the creator is a crafting genius (look him up on youtube - "wyloch"). They take less plastic, are more versatile, faster print time.


I found that Cura 15.04.x was much better than the recommended Cura 2.5.x. My setting for churning out tiles is something like 210C nozzle, 70 mm/s, 55C bed, 0.25 resolution, 0.8 shell, 10% fill, 2mm retraction, 20mm/s retract speed, 60mm/s travel speed, no brim/raft, no supports. You should print at resolution multiples of 0.04 (because of the way the filament feed gear works), ie. 0.08, 0.12, 0.16, 0.2, etc. I'm going to switch to 0.24 resolution for tiles. I do 0.12 for small figures. The printer can reliably print resolution 0.08 right out of the box (lower the speed to ~35 mm/s) but takes a long time to print.

-The black material on the heated bed is call Buildtak - be careful not to puncture it with the supplied putty knife. Get some blunt tools such as https://www.amazon.com/gp/product/B01A81FXMK/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

-you don't need any tape, glue stick, hair spray, for buildtak

-Be sure not to use any acetone or alcohol on Buildtak - both will ruin it.

-Apparently you don't really even need to heat the bed with buildtak, the stuff is super effect with first layer adhesion running at room temp. I ruined my original buildtak by using the supplied putty knife to remove a print that was so super stuck to the bed because I kept it heated. Doesn't hurt to keep it heated though, but be aware heat + buildtak = much adhesion

-That slight lip on the butterfly's bottom layer is due to the settings of first layers being laid down slightly thicker than the others. Sometimes called "elephant's foot" it can also be caused by the nozzle being too close to the bed, which will smush those initial layers more than needed. Closer nozzle = more smushed first layer = better adhesion, but with buildtak you can get away with keeping the nozzle further away, and adjusting your cura settings for a first layer thickness equal to the rest of the print

Ah, well, part of this difference in perspective may be the career path I had -- I've been doing custom electronics off and on for the past 20 years, and a larger number of the electronics design projects I work on are self-contained devices. A different realm than industrial applications. (I also used to do IT/Networking -- in that world, everything was networking gear, servers, and storage devices.)

In some cases, when I talk about real-time, I'm talking about timing relationships that are measured in ones or tens of nanoseconds. The PLC specs I've seen so far talk about cycles times of hundreds of microseconds -- which clearly wouldn't work for those applications requiring sub-microsecond timing. Of course, not everything I do is like that. In fact, most of the work are fine for PLC cycle timescales.

At the start of my career, I worked on a "crane game" arcade machine which would have been trivial to do with a PLC had I known about them then.

It's just that I've spent most of time at a different end of the spectrum than you, I think, and I'm now trying to get a better grasp and understanding of the PLC world.

BTW, I'd love to hear about your background and the path you took to get to working with what you use.

Also, could you point me to where I can read about some of the more "high-grade" systems that you mentioned? I'd really like to learn about them. TIA!

It's an interesting point you make about "selling lots of machines". I can see how if you are selling industrial equipment, using PLC's as building blocks would be the more appropriate approach.

A 3D printer is, in many ways, similar to such an industrial machine in complexity. The most popular forms of building printers today is to use a printer controller built around the Arduino platform (or, more correctly, the Microchip/Atmel Atmega family processors that are used in Arduino). We're talking about a controller board that typically runs 3 PID temperature control loops, 5 axes of motion control, communication with a host computer, reading (and occasionally writing) data to an SD card, running a control panel with LEDs, a graphical LCD, audio, and user inputs, and incorporating the motor driver -- for $35, delivered from Amazon (just to grab the first example I found). By my estimate, at least several tens of thousands of those are sold every year now.

Would I want to run an actual industrial machine with that board? Heck no! :) (They are known fire-starters in some cases, and most of the cheap boards lack hardening that you find in superior devices.)

1. Motor stopper dampeners. https://www.amazon.com/gp/product/B07C7FRLNX/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 These will greatly reduce sound on your machine.
   
2. X and Y motor supports Y = https://www.thingiverse.com/thing:2845950 X = https://www.thingiverse.com/thing:2793110 with dampeners. This'll help alleviate belt tension on the motor/belts and quiet the pritner even more. You'll need some M3x40mm screws for this.
   
3. Flash the firmware with Marlin and enable the heat runaway options. This will stop the printer from burning down your house if a critical error occurs. https://www.printedsolid.com/blogs/news/installing-marlin-1-1-9-on-your-cr-10s-with-mesh-bed-leveling-thermal-protection-better-menu-layout-and-finally-power-resume
   
4. Add a Mirror tile to your bed. Most CR10s beds bow in the middle. Mirrors are totally flat, so just make a mirror your new print bed/print bed base.
   
5. Print the Petsfang upgrade https://www.thingiverse.com/thing:2759439 and get a Noctua 40mm fan. https://www.amazon.com/gp/product/B072JK9GX6/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1 and a 50mm blower fan https://www.amazon.com/gp/product/B071WMHNG5/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1 You can choose if you want the 10 or 20mm noctua fans. Petsfang page says all the screws you'll need.
   
6. Print some support stuff and get some rods to make supports. This'll reduce your print height by 20mm, but it'll greatly stabilize your printer when you do large prints, alleivating weird artifacting when the print gets higher up. https://www.thingiverse.com/thing:2805226
   
7. Get a better Boaing tube. https://www.amazon.com/gp/product/B079P92HN9/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1 (I'm not sure if this is the best out there.)
   
8. A steel wear resistant nozzle if you wanna print things other than PLA/TEPG.
   
9. A PEI plate to make it much easier to get prints off. Preferably a flexible one. https://www.amazon.com/gp/product/B07RDQF7KQ/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1
   
10. A spool mount https://www.thingiverse.com/thing:2440814 which will lets you use bigger spools all while greatly reducing the amount of strain on the extruder and the noise that the filliment makes when it turns.
    
11. Control box cooling fan and base. I've yet to install this one myself as I'm not sure how to wire up the fans, but this'll greatly reduce fan noise and keep the control box super cool. https://www.thingiverse.com/thing:2729888 It'll also remove the problem where if the print goes over 300mm in height where the filiment can sometimes snap due to strain.
    
12. A BLTouch to make bed leveling automatic more or less. I've yet to install this myself. https://www.amazon.com/ANTCLABS-BLTouch-Leveling-Premium-Extension/dp/B076PQG1FF/ref=sr_1_3?keywords=bltouch&qid=1562832293&s=industrial&sr=1-3
    
    ​
    
    Anyone got any others?

Check that the screw that holds the spring arm on your extruder hasn't backed out. The first time I encountered this problem my prints looked exactly like yours and it took me a couple days to figure it out. It will keep happening too, unless you change out the extruder. It's because you can't have that screw too tight or the arm won't apply pressure. So because it's a little loose, it will slowly work out over time, and there's not very many threads engaged in that hole, so the screw can wobble around.

The cheapest fix would be to install an all-metal replacement for around $13. If you look closely at the link I posted, you'll see that the spring arm has an insert for the screw that will allow you to tighten the screw all the way down but still allows the arm to rotate. I haven't had to re-tighten that screw since I installed it. It works great. Also, if you take a 5/32" drill bit and drill out the hole on the arm itself, you can insert a short piece of teflon tubing into it that will protect the filament from the leadscrew. You can just use a regular wood bit and hand drill. Aluminum drills super easy.

FYI, The Monoprice Maker select V2 is a rebranded Wanhao Duplicator i3 V2.1, and its also known as the Coccoon Create in other countries. If you see any of those names, thats your printer.

Your printer doesnt use an E3D V6 hotend, it uses a MK10 hotend.
You can use a V6, but you'll have to print a bracket for it, will probably require some firmware changes with requires flashing a bootloader with an arduino, and may require some additional hardware.

Normally its recommended to just heat up your hotend and carefully pull that plastic off with tweezers, but as your heating cartridge is damaged, that leaves you with two options-

• You can heat it up (oven, lighter, etc) and pull the crap off it. Depending on the formulation of the filament, acetone may help soften it. PLA isn't soluble in acetone but depending on the brand they may use other plasticizers, and those can be, so try soaking it in acetone for a few minutes.
  
  
• Replace the whole hotend. The store I link below has one, but it doesnt look quite right to me and the label isnt right... You can find replacement MK10 hotends on amazon/ebay from china, but if quality is more important than price to you I'd check out Microswiss. Theyre an American company, they make good stuff. You'll still need a heater block though... this one looks like its well made.
  
  I never used it, but this one from Gulfcoast Robotics looks well made as well. this is your whole setup minus a heating cartridge. A whole all metal hotend with nozzle and thermistor for $45 is a deal. They've even got installation instructions linked in the description. Side note- i assume it takes a 1/4in 6.35mm cartridge like the original but you might want to double check with them. You can never go wrong with well-manufactured American components.
  
  Either way you'll need a new heater cartridge (and probably thermistor). Heres a link to a replacement cartridge. Heres a link to a store full of wanhao parts.
  
  This printer uses an unusual sized heater cartridge- 1/4in, AKA 6.35mm.
  Most (E3D) cartridges are 6mm.
  
  Dont get a 6mm cartridge, get a 6.3-6.35mm cartridge. (A 6mm will be too loose and thats one of the reasons that the Anet A8 is such a fire hazard, the heater cartridge can fall out)
  
  Good luck!

OK good info! I can get loads of 3mm hardware easily so no worries there.

I found this hot end and cooling block in the related items: Micro Swiss All Metal Hotend with SLOTTED Cooling Block for Wanhao i3 https://www.amazon.com/dp/B01E1HANLS/ref=cm_sw_r_cp_apa_d.w0xb2R481VR is this good for the price? I'll look online but are there specific enclosure designs that work best?

Also found a laptop cooling fan that is supposed to fit, and borosilicate glass for the bed.

I'm going to start slow with PLA and see where my adventures take me but I might get a reel of ABS too, hopefully I can make RC car parts and stuff like that the some point.

Hey I also new on this, got my printer a month ago, I was super exited as everyone here when receive their printer, I read a LOT while waiting for the printer, so I heard that the stock bed springs are crappy, so I ordered this ones FYSETC Bed springs, also ordered the Aluminium Extruder feeder, and read about the leveling, the paper sheath method, which I think you should already heard about, I did it at the first time the printer gave me a nearly perfect first print (demo dog) , after a few prints and on my third print I came home just to find a mess on my printer, so I did my research again, find out it was bed adhesion, and find out that the best way was glass bed + PEI sheet was the best option, while waiting to arrive I tried to clean the stock bed sheet with mineral spirits (did have rubbing alcohol) but it worsened the adhesion, so I used one adhesion sticker that comes with the overture filament, and again flawless adhesion, at least for the first 4 prints, then again the frustration, I tried some glue stick and worked but it leaves a mess on your print so I decided to try painters tape directly onto the aluminum bed (which lucky for me it is perfectly flat) this is the best adhesion I have tried, problem is also makes a mess with the down face of the print, Finally mi Gass-PEI arrived, (3 days ago), it has a great adhesion but is not perfect, also you have to raise the Z limit switch to compensate the 5~ mm of Glass-PEI, find out that it isn't perfectly flat it has a good adhesion and leaves a very smooth down face, but at some section it does't sticks well and leaves artifacts on the down face, I'm currently working to fix this.

Sorry for the long post, need to talk about my frustration and let you know you are not alone on this, once you manage to make a good print is very satisfying, I have a PETG filament waiting to be used but I don't think is a great idea to try it until a learn more about 3D printing and the Ender.

Thanks for the reply. So far I haven't touched the extruder arm screws so the should be ok but I will check them later tonight.

I have watched the gear and it looks pretty good to my untrained eye. It doesn't appear to be slipping and also doesn't look like its digging in too much. I have had the chance to check out the tube when I was cleaning out the nozzle and hot end and it looks free from any particles.

​

I have purchased https://www.amazon.co.uk/dp/B07DC594D6/ref=cm_sw_em_r_mt_dp_U_1NwwCb51ACY2Q and it should be arriving today. So I will try to use https://www.thingiverse.com/thing:3203831 to stop any future issues.

​

I will go through the the procedure shown in the video you link and hopefully, this will help.

​

All of this as well as Kamilon's should hopefully resolve my issues.

I had this happen on mine. Scrape it off the best you can and use Goo-Gone to purge the remaining adhesive. Once you have a clean metal bed, painters tape works great and is cheap and easy to replace. If you are feeling up to it, you can install a glass bed on top of the metal like I did, just make sure to level the bed right if you do because the glass adds extra space. Then use a purple glue stick for some extra adhesion if you need it!

​

Here is the link to the bed I am using, and I am completely satisfied so far -> https://www.amazon.com/Borosilicate-Polished-Corners-Monoprice-Select/dp/B075XJ5ZP1/ref=sr_1_fkmr2_1?ie=UTF8&qid=1549203064&sr=8-1-fkmr2&keywords=monoprice+mini+v2+glass+bed

Paying someone to do the full set will definitely run you more than the cost of this printer. It's the printer I have. It's a bit finnicky, but the price is right, and it prints well enough for me! I'd also highly recommend getting a glass bed for it. It's stupid easy to install the glass bed (you just lower the normal bed and clip the glass to it with binder clips), and it makes the prints come loose soooo much easier. You can also have a hardware store cut the glass for you and it will be a bit cheaper than that Amazon link.

I will say, though: I only recommend buying a 3D printer if you're willing to devote some time to it. It's not like an InkJet where you plug it in and it just works. It takes calibration, and learning which settings work best. You'll have to do some research to get the best quality for your prints.

Thanks! I got my carriage plate from Amazon, this one specifically: https://www.amazon.com/gp/product/B07B251KBS

The buildtak that came on it was awesome for about 40 days or so of print time. No issues at all, everything stuck real nice but popped off easily with a woodworking chisel. Eventually it started to wear smooth, and the plate it's attached to started to warp pretty bad in the middle. That's when I switched to glass + gluestick. btw I put my glass right on top of the old buildtak rather than try to remove it because it was really stuck on there.

As for the carriage plate, things were good for around 70 days, but eventually what happened was the original plate bent up in the corners so bad that I wasn't able to keep the bed level for more than a single print, and then suddenly I couldn't level anything at all. Since installing the carriage plate, I haven't leveled it again yet.

I'm going to suck it up and print that dii cooler too lol. Might have a friend do my first one since he has awesome cooling already.

Everything he said is spot on. I have 4 cheap Chinese printers and those are all the recommended upgrades regardless of the brand.

I recommend this power supply. It can provide 50% more power and has a cooling fan.

These mosfets have worked very well for me and lowered bed heating times significantly as well as make your printer a lot safer.

Personally I haven't had any issues with the bed connector, but maybe some epoxy or hot glue would keep the wires from moving around too much.

One of the best upgrades I did was to flash Marlin onto the board as the stock firmware is kind of crappy.
This also allows the use of a Inductive proximity sensor which makes leveling the bed significantly easier.

The bearings he recommended, the Drylin ones, will make the movements of your printer a little smoother and a lot quieter.

The belts stretch. The ones from China are rarely reinforced. I'm lazy so i just tighten them every so often. But it would be worthwhile to just start with the higher end reinforced belts.

That aside, once your printer is up and running and somewhat calibrated, head over to thingiverse and search for your printer. There are thousands of upgrades available.

Good luck!

Couple of thoughts -

• Preheat the bed to the print temp before leveling. On my MSP, the bed rises considerably depending on whether it's hot or cold.
  
• When leveling, use printer paper. Business cards are too thick, you really want that nozzle close to the bed so it's smooshing that first layer down.
  
• Preheat the bed for several minutes before starting the print
  
  Also, it will cost you some money but replacing the Y carriage and adding a good glass plate help too. I'll edit this in a sec with the links.
  
  Edit!
  
  Glass bed: https://www.amazon.com/gp/product/B07B2YLWF9
  Y-carriage: https://www.amazon.com/gp/product/B07B251KBS
  
  I originally was using thermal pads between the glass and the print surface. Eventually I found I had better results by skipping the pads, peeling off the print surface, and putting the glass directly on the metal bed with small binder clips on the left and right edges. I use Elmer's purple glue sticks for adhesion and rough it up with a sanding block between prints. Make sure your Y axis rods are level, as well.
  
  Good luck!
  
  

So far working with the Anet A8 has been an extreme lesson in patience. It's honestly a bad printer but if you're willing to spend time and a little money, you can make it decent. First up should be fire safety. Immediately upgrade to the latest version of Marlin and install a mosfet for at least the bed, if not both the bed and hot end.

I would also recommend ordering new bearings before assembling the printer. The ones it comes with are pure garbage and for $10 it's an easy purchase. Another thing that might be worth investing in immediately is better belts.

After it's assembled and you can print well enough print an X belt tensioner and a Y belt tensioner. After that it might not hurt to print some braces for the weak acrylic frame. If you're hardcore about the frame check out the Anet AM8 upgrade which replaces the acrylic one with metal for about $60.

Good luck!

>Any chance you could be more specific on the dupont connectors required?

You'll need 4 pin dupont housings and dupont female connectors and a crimper for them. That's assuming you have something to strip the wires as well. You can find the dupont female pins and housings cheaper places like aliexpress, ebay, etc.. but I recommend buying a quality crimper instead of whatever is the cheapest you can find as a quality tool will make the job a lot easier. If you're really strapped for cash, there's video's of people crimping dupont connectors with pliers online instead of the crimp tool.

>So <motor><cA> => <cB><cable><cC> => <cD><RAMPS board>

The wires transfer over to the same place from melzi to ramps, and pretty much any board. You'll have a X endstop, y endstop, z endstop, then connectors for the X motor Y motor Z motor and extruder motor, and so on and so forth. A ramps guide will help you visualize what to connect where.

>Any idea how big a cable for the power?

IIRC, the stock wires at 18ga, which is fine for the ramps board since it only draws 5A for all the motors, hotend, etc. The only other larger gauge connectors are for the heatbed, which I believe are also stock 18GA. FWIW, I'd go with a external mosfet instead of using the ramps on board ones which are rated for 11A, which is just within spec of what the bed draws.

Here is my CR-10S.

I added the Petsfang fan fang. Added this fan to the fang.

I added these Z-Axis braces. Added these LEDs to the Z-Braces.

I'm printing on a mirror tile with a sheet of PEI bonded to it.

Last week I added the TH3D EZABL and have been encouraged by the results. It creates a Z-offset map of the build plate before every print. I can see the Z-steppers move during X-Y moves so I can tell it's working. Manual bed-leveling was working OK for smaller prints, but I could never get all 4 corners to agree with the center height. I suspect my aluminum bed plate is shaped like a Pringles chip.
I really like the Marlin Firmware over the OEM version. I don't mind not having auto-resume since I plugged my printer into a UPS system.

Right now my printer is about 20 hours into a 60-hour print of a T-Rex skull. I've been really happy with this printer! It was my first and I've been having a ball with it.

The build plate on the Ender is made of aluminum and is infamous for warping under heat, or just being slightly bent out of the box. Whereas a glass bed sits on top of the aluminum build plate.

Most people use glass for the smooth surface, but many Ender owners choose one simply because it provides a level printing surface. Often people will even put the print mat that comes stock on top of the glass, giving them the adhesion benefits of the mat, with the level benefits of the glass.

Some will tell you that a mirror or similar piece of hardware store glass will work fine, but it is known to shatter due to the heating and cooling process. For about $20 on Amazon, an actual Creality borosilicate plate is well worth the cost. (on Amazon )

Extruder: get a microswiss hotend for it will be able to print flexible and other materials.
Parts cooling: Upgrade to the petsfang 5015 mod for better print cooling.
Auto bed leveling: Get the TH3D ezabl sensor for great bed leveling.

Did you print using the generic filament they give you? I also just purchased this printer and printed the same thing but I used Hatchbox filament and it printed perfect. I wish I had a better answer but I'm also new to printing. If you haven't ordered one of these yet https://www.amazon.com/gp/product/B01C3HEQZC/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 order it right meow well worth the $$ and a glass bed will make your print bottoms butter smooth https://www.amazon.com/gp/product/B00QQ5Q3BI/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

No problem, stuff happens. Anyway, if you want the bed to be totally static, it's rare you see that outside of delta designs. Typically the bed moves on the Z axis with CoreXY machines, just because I'm pretty sure moving the whole gantry would be a pretty strenuous process for the motor. The only kind of cartesian machine I can think of right now where all of the movement is done on the axes is a design by Printrbot meant to make an effectively infinitely extendable monstrous printer, called the Big E, so perhaps you could look to that for inspiration?


As for your electronics, I'd say start with a basic RAMPS board. I bought this recently, and it seems solid. I can't vouch for its quality yet as I've yet to actually use it. Given the sheer size of a machine you want to build, I'd think you might want to look into NEMA23s, though, and those require a beefier board, so I'm not sure where you'd begin to look for something like that. I think your best bet right now is to make a new post, to get some visibility.

The pei sheet I got from amazon (https://smile.amazon.com/gp/aw/d/B074XLD5QH/ref=ppx_yo_mob_b_track_package_o0_img?ie=UTF8&psc=1) didn’t have the adhesive pre-applied, it was just smooth on both sides with a thin film over it for protection, and a 3m double sided tape was included in the package. If yours has adhesive already on it, I’m not sure about the temp limit on the film, but suspect you’re right that it isn’t very high.

I had been thinking about just clipping it on before it arrived, but it was thin and flexible enough that I’m pretty sure it would get pulled up slightly by larger prints. I had considered just buying a 1cm thick sheet from McMaster Carr or somewhere rather than one being marketed for 3D printing, I think you could definitely clip that since it would be rigid, but I was concerned if it didn’t show up perfectly flat I wouldn’t be able to do anything about it.

I watched a few videos before putting it on, and it was actually easier than I expected. Even though it has some flex to it, it’s ridged enough that there wasn’t really any issues with bubbles under the pei sheet itself. The adhesive bubbled a little when I put it on the glass, but it wasn’t very hard to either work them out, or in a few cases just poke them with an xacto. The hardest part was actually removing the plastic from the top of the adhesive without peeling the whole thing off the glass, but once done the pei went on nicely. If you’ve seen them mounted before, it’s normal for it to look kind of mottled with some visible pockets of air, but still be flat with no significant bubbles. I checked for flatness and it was good. I will take a picture later and update this so you can see what I mean.

I’m jealous of your 2 backups, I have been afraid to print anything but PLA and be unable to get it off. I ended up with the pei because I kept destroying various stick on surfaces by squishing the first layer of PETG too much and ending up with it welded on.

these are the bushings that most people talk about for this printer. Igus doesn't make sleeved bushings that can fit as a drop-in replacement for the LM8UU bearings. IIRC last time I did the research, I found they do sell sleeved bushings that will fit in the Prusa (as in they have the correct outer diameter and length), but not with the correct inner diameter needed for the stock smooth rods. So if you went that route you'd need to not only get new bushings across the board, but you'd also need new rods everywhere too, and that pushed the cost up to about $75 when I last looked.

Honestly for the price I'm not really upset that I tried them, but I absolutely learned to just stick with stock unless it's giving me major issues.

Getting the y axis to move smoothly was a challenge, as the stock u-bolts would squeeze it vertically and leave wiggle room horizontally, which would allow the plate to cock sideways a bit and bind. With some finagling I was able to get it working, but there was a lot more resistance than I would have liked, it was consistent resistance across the whole range of movement, but it was still more than I wanted. The X axis I never got them fully working, as ANY force parallel to the smooth rods (but slightly offset in one direction) would cause binding by cocking the x carriage one way or another.



But don't let me be all doom and gloom, if someone is able to get them working and can talk about their experience, I'd love to hear! And I'm sure there are people out there who value the silence they provide over some unreliability or increased maintenance/tuning required, but I was overall unhappy with them and I won't try it again.

Nice ! I can see you've done your homework lol, all good choices. I'll just give you a few suggestions then since you've pretty much got it covered. The springs I used on my enders were these: https://www.amazon.com/gp/product/B07FY47BX7/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 You might need longer screws, not sure about that, but you can get those at any hardware store, probably around 35mm m3 screws should do the trick. And the motor vibration dampers i used were these: https://www.amazon.com/gp/product/B07C7FRLNX/ref=oh_aui_search_asin_title?ie=UTF8&psc=1 you don't need them on the z-axis, just the x and y. As far as smoothers go, I think the creality boards currently use a4988 stepper drivers, so you'd probably not see any benefit from tl smoothers. I'd definitely recommend the glass bed, since ender 3 print beds are almost always warped to some extent which can make leveling the bed a real pain in the ass. The hardened steel nozzle is cool, just be aware it's not as good at transferring heat to the filament as a brass nozzle, so it prints slower, and it's only useful if you're planning on using abrasive filament like carbon fiber or glow in the dark filament. Pla, petg, wood pla, and abs don't need it. You can actually print anything you want with a brass nozzle, you'd just replace it more often depending on how much abrasive filament you use. Also, don't know which fan shroud you're planning on, but the bullseye is very good and it uses the stock fan : https://www.thingiverse.com/thing:2759439

Sorry about the wall of text lol.

You get enough from these two products to upgrade more than one printer as well, I love capricorn tubing, I wish it was just standard with every printer also just double checking that you're using 1.75mm filament I don't know the CR10 that well if that's an option that wont work with these products if you're using a larger filament. Good Luck!

Hotend replacement:
I replaced the stock hotend/PTFE tube setup with an all-metal Micro Swiss hotend ($50):Amazon link to the Micro Swiss all-metal hotend kit: https://amazon.com/gp/product/B01E1HANLS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Bed leveling:

1. Most importantly, I purchased a glass bed to eliminate the never-really-level printbed.Amazon link to the borosilicate glass bed ($25): https://amazon.com/gp/product/B07BHG5HCV/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
   
   
2. Since that didn't I completely fix the warped bed issue, I also replaced the aluminum Y-carriage underneath with a thicker, stronger carriage and my bed leveling is now perfect. I still re-level before every print just in case, and now never have leveling-related problems.Amazon link to the aluminum Y-carriage ($28): https://amazon.com/gp/product/B07B251KBS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
   
   Frame Stabilization:
   I printed the parts, and purchased the hardware at Home Depot for the Z-brace mod, which stabilized the printer frame:Thingiverse link for Z-brace mod for I3 Plus: https://www.thingiverse.com/thing:1653631(note the original Thingiverse link in comments, which is required for the other Z-brace parts: https://www.thingiverse.com/thing:921948)
   
   Cooling:
   I printed a Dii Cooler in PETG and replaced the stock cooler with one of those 24V "squirrel cage" fans, which provided much better cooling for all sides of my prints. Before that it really only cooled the front of prints, leaving the sides and especially the rear of prints looking pretty bad.Thingiverse link for Dii Cooler for i3 Plus: https://www.thingiverse.com/thing:1025471

I struggled with adhesion for the first couple weeks of printing. Then I swapped my stock bed for a glass + PEI combo. Got the flatness of the glass + the adhesion of the PEI. Once the plate cools down a few degrees, the parts come right off. No need for sticky hairspray to get things to stick, and no need to put the bed in the freezer to get things to unstick. Best upgrade I’ve made on my ender 3 (~$30 total). Always wipe down with isopropyl alcohol in between prints for best adhesion.

Tip: I also recommend gently wet sanding the PEI. Helps with adhesion and creates a very nice matte finish on the first layer.

I use a thin metal spatula for removing prints from the bed. It often tears the masking tape, but that's OK - That encourages me to put down fresh tape, and fresh tape makes for better prints.

Here is a list of things that people will always need, I understand you can't stock everything as overhead is an issue with retail, and storage as well, but most of these are small enough that they can occupy the shelf space you currently have. As for the larger things, like the 2020 extrusions, you could sell them in common lengths of 500mm and 1000mm and let the customer cut them down to the size they need, or just don't carry these at all. It's not a niche item, but for a retail store like you it would be hard to store and maintain, but man, would it be nice to be able to get those locally if i needed a piece for a project instead of having to wait on mail order.

  this is just a basic list, others have listed other things as well, Steppers, Belts, Pulleys, Bearings etc. If you want 3d printing as a reason for other people to go to your store, these items will satisfy the need. Just keep prices fair, I have no issue paying a bit more compared to amazon to get it today.
  

Idk about $180, but you can definitely save a bit of money if you order it from the warehouse in China. It just takes longer to arrive, and I personally feel more comfortable dealing with Amazon, as compared to eBay or Alibaba.

OP, here are a few purchasing option links. Also, I would go with the glass bed option if I were you. The eBay link has the option to choose "Ender 3 + Glass Bed" at what looks like no extra cost. Otherwise, you can buy the glass bed separately for less than $20.

PEI Bed surface (has to date been the best upgrade): https://smile.amazon.com/gp/product/B07GSJSDWR/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1
and if you don't have a glass: https://smile.amazon.com/Creality-Ender-Glass-Upgraded-235x235x4mm/dp/B07RD6D2ZQ/ref=sr_1_5?keywords=creality+glass&qid=1571456745&sr=8-5


I'd recommend applying the pei in the smooth side of the glass that way you can flip it over to have the textured side if you want.

I can't say this is what the "best" method is, just what has worked for me in the past:

• Coat with epoxy and/or use epoxy putty to deal with any large gaps or to make up for rough edges.
  
  
• Let it dry overnight
  
  
• Then LOTS of sanding. So, so much sanding. I honestly love this part, so carthartic.
  
  
• Spray paint automotive primer. I think the reason it has to be this specific type is because it does a good job of filling in the cracks and holes. I also give it a few rounds of sanding with a 220 grit sandpaper after priming to give it a silky smooth surface (yes, you can sand this type of primer!)
  
  
  My biggest gripe with 3D printing was that the ridges were always present. This process makes it so the ridges are non-existent and easier to paint!
  
  Edit: I should mention I've mostly worked with large scale cosplay props. This process might not work for everything, like you probably don't need to put epoxy on small stuff.

Wanhao i3 Duplicator v2.1 by way of Amazon.

I have two of them, easy to use and improve machine.

Here's a Facebook group dedicated to them.

If you get this printer, this is a highly recommended upgrade. It's a hardened steel nozzle and slotted cooling block kit. Very easy to install, improves holding a given temp in the hot end.

And here is a good deal on filament that's made in America, a grab bag of four rolls for $60, your choice on type.

Most people are telling you it can't be done, but the truth is there are food grade filaments and techniques for printing food safe parts. I don't recommend you do this, but at the same time I'm happy to provide the following information.

• Don't print with a brass nozzle, as it probably contains lead.
  
• PETG is food safe, and can be sterilized.
  
  https://all3dp.com/food-safe-3d-printing-material-filament-plastic/
  
  https://www.3dhubs.com/talk/thread/overview-food-safe-3d-printing-materials
  
  Slightly related, I've emailed Smooth-On to confirm their XTC-3D is not food grade.
  

Sure, no problem. I'll give you a bit more info as it may be relevant :)

1. I use a 3 mm borosilicate glass bed by Go 3D. I started with dollarstore glass which worked well enough but it wasn't thick enough to compensate for my curved bed.
   
2. I washed it in hot water and soap. I had to use a razor blade to scrape off some tough weird spots that were likely from the manufacturing process. I got it squeaky clean and let it air-dry.
   
3. Meanwhile, I removed the buildtak and adhesive from the printer. It didn't take long. The trick was heating the bed up to 100 and carefully using a razor blade scraper. I have more info on this; ask if you're interested.
   
4. I installed the glass bed, making sure I didn't touch the surface more than necessary.
   
5. I cleaned it again with 70% isopropyl and a glasses cleaning cloth (I picked up a bulk pack of them from Amazon). The isopropyl is in a spritz bottle that I bought at a local drugstore. I top it up using a bigger refill bottle.
   
6. And that's basically it. I repeat #5 every time I print. Spritz, scrub a bit with the cloth over where the previous print was, and done. It takes maybe 10 seconds. I've been printing on it for about 2 months now and haven't taken it off to re-clean with soap and water. Some people say to use acetone, but I've had luck with just 70% iso.
   
   That said, the biggest contributing factor to getting my prints to stick was the leveling. Once I nailed the leveling, I haven't had a failed print due to poor adhesion. Failures due to other things, sure. But not because of the glass :)

I recently went through exactly this same situation. I was ready to upgrade to a microswiss all-metal hotend and the catastrophic failure of the print leaving gunk all over my heater block forced the issue. In my case, I opted to replace everything I could including the thermistor and heating element. They are both very inexpensive and you should have a spare laying around anyway in case you need one in a hurry. So...how to clean your heating block...

Fire. Seriously. I used a combination of blowtorch and solvent to remove all the gunk (and mine was a LOT worse than yours...it basically encapsulated one entire end of my heater block, entombing the thermistor, heater and associated wiring).

I used your typical propane torch, holding my heater block in a vise or vise grips. I'd heat it up then quickly wipe away the melted PLA with a clean cloth. Heat, repeat. Then I'd soak the whole thing in some solvent (acetone, MEK, etc). Repeat until clean. Pay careful attention to the tiny setscrew that holds the heater in place...work it free with a hex wrench while it is hot...chances are you got some PLA stuck on there, too. Obviously be super careful when you do this. Ventilation, fire-extinguisher handy, your mom on speed-dial.

When you replace the thermistor and heating element you'll need to do some soldering. This is pretty unavoidable. Those elements come with very long wires attached to them and the Wanhao/MP print heat doesn't need that length. Clip it short, make good solders and use heatshrink over your joints. For the thermistor I simply cut out the center section of the wire and spliced the connector back to the component at the length i needed.

Now, when you put it all back together you will have the option of re-wrapping the heater block with cotton and Kapton tape. People seem split on if this is necessary, but since I'd battled heat creep before I didn't want to introduce any more heat up the block...so I opted to do it. It's a bit tricky if you get the non-punched cotton strips like I did. Luckily I had hole punches handy to make the provision for the hotend and nozzle to get thru the insulation. If you don't have these tools (or don't quite know how to do it), i'd shop around for pre-punched sets.

good luck. Let me know if you need any more help.

Nozzles

PTFE. This is the cadillac option. Cheaper tubing is very cheap, like $5 for 5 feet or something.

I didn't mention these as I haven't installed them, but stepper dampeners. Please see the stickied thread on /r/ender3 about these, if you want to order them!

The springs I ordered. Note: I couldn't quite replace the one where the wires attach to the bed. I didn't play around too much, I just left that one on there. The other three have held solid, and the next time I'm adjusting my bed, I'll try to put that one on there as well.

Hope that helps!

Edit: Reddit markdown not liking my links, I'll try to fix them

Look at something like this :https://www.amazon.com/dp/B00VB1U886?ref=yo_pop_ma_swf
I used to just wreck prints trying to get it off with the stock scraper they send with the printer. It’s a thinner edge so it really seems to pop it off the bed a lot easier. I got that second one I linked a few posts back and I don’t use one of the tools but the longer one I’ll use after using the first tool on big prints outside of that this one really seems to get under prints with out to much effort.

Another solution that I have heard good results with but I not personally use is this stuff: https://www.amazon.com/dp/B01N2JGTWJ/ref=cm_sw_r_cp_api_xQdWAb79FZS82
It’s on my list to try but my current printer doesn’t really need anything to help with binding or release from the bed. Now I did pick up a bed surface called geckotek : www.geckotek.co it’s supposed to be a bed pad like on the printer already but is supposed to just release prints after the bed cools down. Might run around $20 so it’s not to bad of a loss not sure when I’ll get around to installing it but could be better than the current surface it has now.


For a camera/smart switch look into a octopi setup. It uses a raspberry pi but it acts as a print controller. From what I heard is you can start/stop prints as well as upload prints you sliced and just run it from there. But you are supposed to be able to remote view it with a camera as well. I just never got around to setting one up but I do have everything if I ever need it. I normally run my long prints on the days I know I’m home but I normally don’t have to many issues though I have failures in the middle of the night but with me being close by I can catch it before any chance of damage. I do have my printer on a ups but I think it’s on the end of its life span so I will most likely need to replace it or the batteries later this year.

I replaced the stock glass with mirrored tiles from Home Depot. I used to use tape and glue sticks but read a comment on how much better PEI sheets were to print on. No more glue or tape, just rub it down with rubbing alcohol between prints.

It sticks very well when heated up, and comes off almost effortlessly when cooled down. You also get a shiny surface on the part touching the PEI sheet which is nice. Well worth $21 from Amazon.

The Monoprice maker select v2(.1?) Is a little over $300 on Amazon, but other than that, it fits all of your other needs. It uses standard metric screws and such, so fixing and modding the printer is easy. It's also has a respectable build volume of 200mm^2 and a height of 180mm, which is nice to have. It comes mostly assembled: you just need to use 4 included screws to attatch the gantry to the base and 2 more to attach the filament holder. It took me no time at all to start a test print. I'm coming up on six months with my printer now, and it hasn't given out on me once. For the best prints, you'll want to do some mods, but only the absolutely necessary MOSFET mod requires non-printed hardware that isn't just screws and nuts (or the standard M8 threaded rod used in AzzA's Z-brace mod).
Tl;dr: Monoprice Maker Select v2 on Amazon, order a MOSFET to go with it, 10/10 IGN

So far, comments have focused on the glass bed. FWIW, your bed seems similar to mine:

https://www.amazon.com/dp/B07RD6D2ZQ

I've had at least 1000 successful prints on the "dimpled" side of this bed and have never used any kind of adhesion aid. I clean it with a quick wipe of alcohol (for one or two seconds) between prints and it's good to go again.

My guess is that you still haven't managed to level your bed properly. Can you upload a pic of one of your attempts at a first layer? That would help a lot.

I'm noticing a trend involving multi-tailed foxes...

Very cool, but I have a question. Do you think the filament would still be sensitive enough to heat if it was coated in epoxy such as this stuff to give it a nicer, more "sculpture"-like finish? It'd be fun to have something like this, but I typically do everything I can to obscure print lines on display pieces. Can't prime or paint this though, obviously.

What you absolutely MUSTTTTTTT!!!! order? Nothing. The printer works as is. But if you want to do yourself a favour, here's a list of what I consider essentials:


- New springs, both bed and extruder. I don't have a link for an extruder one as I upgraded my entire extruder drive frame and that came with a better spring

- A new removable bed. Creality glass bed or glass with a PEI sheet is my bed of choice

- Thermal pad to avoid the annoying bed clamps. Cut squares out of it, lay them in a checkered pattern alternating between thermal pad and nothing and place your bed on top. They will hold the bed in place and help with heating

- Stepper dampers if your printer is anywhere near where you spend your time, it sounds like a bloody jackhammer right out of the box

- New tube fittings, the stock ones are terrible and will give out in a matter of weeks at best. They also barely hold onto the tube

There are a ton of other great upgrades, but I think a good idea is to get a feel for it yourself.

What you can do, however, is check out some printable upgrades. I have this thread where people contributed with their choice of printable upgrades. It's a great list you can refer to later. Essentials on that are the fan guard and LCD back cover simply because the Ender 3 as is has the fan and back of the LCD exposed and that makes it crazy vulnerable to dust and gook damage

Actually, the parts are pretty standard, so it doesn't really matter where you buy from.

I bought them from various sources (electronics markets, amazon, and some local shops), so my links are just to be seen as examples:

• PSU Switching Power Supply 400W 12V 33A for 3D Printer Kits 115V/230V S-400-12 (got mine locally for 20€)
  
• MOSFET BIQU Heat Bed Power Module Expansion Hot Bed MOS Tube for 3D Printer or alternatively TriGorilla 3D Printer Heating Controller MKS MOSFET for Heatbed Extruder MOS Module (this one is huge, but powerful)
  
• Power socket & switch https://www.amazon.com/URBEST-Module-Switch-Certification-Socket/dp/B00ME5YAPK - here any 10A 250V 3 Pin IEC320 C14 type will do
  
• T-Belt RepRap Champion 5 Meter 6mm Width GT2 Timing Belt for Reprap Delta 3D Printer Kossel Rostock
  
• Pulleys BIQU GT2 20Teeth 3mm Bore Aluminum Timing Belt Idler Pulley for 3D Printer 6mm Width Timing Belt (Pack of 5pcs)
  
• Bushings 3D Printer Solid Polymer LM8UU Bearing 8mm shaft - Igus Drylin RJ4JP-01-08 for Anet A8 Prusa i3 3D Printer RepRap (warning: you need 8 pcs of these bushings. Couldn't find any listed offer with 8)
  
• Borosilicate Glass Signstek 3D Printer MK2 MK3 Heated Bed Tempered Borosilicate Glass Plate 2132003mm
  
  Printed upgrades:
  
  
• Z-Endstop for 3mm Glass
  
• Improved Fan duct or Fan duct for Anet A6 because my original fell out and killed a print as well as the fan mounting plate
  
• PSU cover
  
• Y-Belt holder
  
• Table nut and cover spring
  
• Anet A6 Dual Mosfet Holder (works only for the small MOSFETs)
  
• Z-axis calibration spacer (not really necessary but nice to have) - print two
  
  There is one small error in the assembly videos: The bed mounting plate (the H-shaped thing) is mounted upside down in the video. The bar that goes across the axes and connects both outer plates should be under the plates, not above as in the assembly videos.
  

I've been experimenting with different things.

Plastruct Plastic Weld makes a pretty solid bond. The only time I've had trouble with it is lately while trying to bond sections of a sword blade that are 0.3" thick and 3" wide. The sections with the most stress on them can snap if I let it flex enough.

I used Gorilla Glue to glue together pieces that left gaps. It expands and fills, so that was handy. The bond seemed strong, so I'm going to try that on the blade pieces next.

I've also used Loctite gel control super glue and it worked fairly well, but I don't believe the bond is as strong as Plastic Weld.

As for finishing prints, my current method is to use XTC 3D to smooth the print. After that, I prime, sand, and paint using spray paints. I will probably get an airbrush soon to try for nicer looking paint jobs.

I actually replaced my whole extrusion path.

First, I found that the spring in the stock extruder assembly would fatigue resulting in under extrusion and jams. The BMG is a little pricey but worth it IMO. Comes with pretty good instructions.

Second, I switched to a Micro-swiss all metal hot-end. I probably didn't need to do this - given I almost never print high-temp materials but did it anyway.

Last, cheapest, and not least, Capricorn Tubing. Do not underestimate the difference this can make.

If you're up to the challenge, I highly recommend a BLTouch. It completely solved my first layer woes (warped bed on my CR-10s).

Its a great printer. Upgrade your springs and get an aluminum extruder. Those two things were so cheap, but definitely made a difference for me. I use a glass bed with a PEI sheet and have been very happy with it. I use eSun PLA Pro for my minis. Check out Tomb of 3d Printed Horros for their cura profiles and tips!

i have an ender 3 pro and after saying no to any upgrades I finally started to see what everyone is talking about 6 months down the road. here is a list of things that you will see a lot of you tubers tell you to replace. the YouTube channel Tomb of 3D Printed Horrors is a great resource for everything about the ender 3.

1. new boden tube and couplings that are alot better to use then stock https://www.amazon.com/gp/product/B07DC594D6/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
   
2. THIS IS A MUST HAVE! a new metal extruder (eliminates a crap ton of extrusion issues) https://www.amazon.com/gp/product/B079JZ374W/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
   
3. Glass bed (best bed adhesion with 0 cleanup) this is optional but does solve a ton of issues down the road https://www.amazon.com/gp/product/B07JKGNB6W/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1
   
4. extra nozzles in a variety of sizes (not needed but nice to play with different sizes and to clear any clogs fast you can just replace the nozzle....i run .2, .4, and .8) https://www.amazon.com/gp/product/B07JPZ7TNX/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
   
   the YouTube Chanel Tomb of 3D Printed Horrors has a step by step build guide for your ender 3 ( i used it for mine) he will recommend most of this list as well. He also has other videos on the slicer settings you will use for Cura. for D&D models you can use this google doc list https://docs.google.com/spreadsheets/d/1PemvBH7LC-hm4KoeA8OXVu5_k963Vpmw7kOEA_1tzWs/edit?pli=1#gid=0

Hi, I have the tempered glass one with ridges, they don't say it needs anything. I think If you use a glue-stick on it would stick forever. When I had it placed good it worked without anything, but something happend and it unleveled itself.
https://www.amazon.com/Creality-3D-Platform-Tempered-235x235x3mm/dp/B07FSM8DK9/ref=sr_1_4?keywords=ender+3+glass+bed&qid=1566487149&s=industrial&sr=1-4

The idea on using the glass to space it is great! I will try it!

Thankyou for respoding :)

I LOVE MY ENDER 3'S. I have one running stock everything (except the bed) and the other is well, an ender 3 in name only now. (I know you mentioned you are in the EU, but I have provided links to my sources for US based distributors)

Note that I didn't buy this flashing kit, but this one seems to have everything you need to get a bootloader onboard the Ender. What happens is you go through a bunch of steps to attach this so the printer and then put a bootloader onto the Ender 3 board. You only have to do that one time, then you can update the firmware as often as you want - typically via a USB cable. I have Octoprint installed, so I can flash my firmware on my basement printers from my upstairs computer using wifi. Super easy and handy.

Set it up and use the existing hotend to print out a z-brace kit, I printed for days without it but it really helps. This will also help you understand and appreciate the difference when you upgrade the hotend :) People run into the connector problem when heating the bed up for ABS and other higher-temp filaments, I have had no issue running PLA. I also never leave the house when it's running, but that's a general distrust of robots thing. Now, with z-braces, allmetal hotend, and a pei sheet, I have had awesome prints every time.

Your hot end is not able to extrude the amount of filament you are trying to push into it.

you need to do one (or more) of the following:


the hot end hotter. ^1
to print slower. ^1
to sort out a clog (either full or partial.) ^2
calibrate the E steps and flow rate. ^3




----------------------------------------------------------------------------------------------------------------------------

^1
Not all filaments are made equal, I've had rolls of PLA that print fine fast at 210, then others that will gum up the hot end at speed. The printer takes time getting up to speed so some filaments look fine when printing slow or small models. Long paths show this failure I've had filament refuse to print cleanly unless the hot end is set somewhere on the upper side of 225-235 - going to extremes with temp should only be considered after ruling out a clog e.g. a/b the misbehaving filament with another brand and have the other brand work fine at the lower temps/same speed.


^2
(make sure to replace the stock bowden couplers they are crap allow the tube to back out and will cause no end of clogs, something like https://www.amazon.co.uk/dp/B07DC594D6/)
Follow this video on how to replace the nozzle paying close attention to the temperature everything is done at and the procedure to make sure the tube is snug with the nozzle. (to loose and you get goo, too tight and you'll squish the bowden tube and get clogs) https://www.youtube.com/watch?v=FRzsGttNMyk
If you need to clean your nozzle (a big bag of 0.4 nozzles is a worthwhile investment and you can find them cheap on amazon) hold the nozzle in pliers and cooking off everything over a gas burner, use cocktail sticks to remove the majority of the gunk, get the rest out with the acupuncture needle the printer came with. - Needless to say this is all very hot and the plastic can catch fire and drip, so do it somewhere or over something non flammable and easy to clean, I do it over a ceramic stove top with gas burners.

I'd make an addendum to the above instructions, ideally E-steps should be calibrated without filament running to the hot end, and the altered steps would look something like:

hot end at temp
remove filament completely
undo the bowden coupler
insert filament slightly into feeder,
cut filament flush at the hole the bowden coupler was in
extrude, measure, math, set e-steps,
cut filament flush
extrude, measure, math, set e-steps, save settings.

This way completely removes any sort of partial clog, variance in filament diameter size or issues downstream from the feeder assembly.

I bought this extruder feed from Amazon to replace my plastic one.

I checked a YouTube video real quick and then went for it. It seemed like a pretty straightforward install.

That said, now I look at it, the arm seems canted a bit, almost as if the screw with the bearing on it isn't in all the way? It's in as far as it will go.

I had one short countersunk screw (M2 I think) and a lock washer leftover. Couldn't think of where a lock washer would be useful for this assembly, and the stock one didn't have a lock washer anywhere, but if someone knows where it goes, or anything else to ensure this is on correctly, please let me know.

That said, it seems to be extruding just fine, I've done a couple of test prints and nothing seems amiss.

That's a very good point. I'm confident in my soldering skills, I neglected that others may not be. I have seen a few FET's out in the wild. I'm not sure if they are all created equally.

I'm aware of the reprap one:
http://www.reprap.me/power-expander.html
and the Amazon Trigorilla one:
https://www.amazon.com/TriGorilla-Printer-Heating-Controller-Extruder/dp/B01HCVJ3K2/ref=sr_1_1?ie=UTF8&qid=1482884825&sr=8-1&keywords=3d+printer+mosfet

Can anyone chime in on the best Mosfet solution for those that don't have the skills or want to possibly void their warranty?

problems so far havent really been anything serious, i bought the upgrades before i even built it so i cant really talk for the stock version

Upgrades i bought for it

• Silicone Heated Bed From Folgertech($25)
  
• Tri Gorilla Mosfet($19)
  
• Custom cut piece of glass from lowes ($6)
  
• Microswiss CR10 All Metal Hotend bought the CR10 version because they use the exact same hotend and its a direct replacement
  
  other than that havent really had any problems with it its been a great printer so far, i am going to start printing some upgrades for it soon but its printing really nicely so far, if you do end up getting it ive got my s3d profiles i could email you ive got them looking pretty good, the retraction was one of the longest settings to get dialed in for me as this is my first bowden tube printer
  
  if you have any more questions let me know

I bought a regular glass bed off amazon and really liked that but the textured surface started to fail after a while and I didn't like having to clean off adhesives or hairspray. I got this PEI build surface from amazon and stuck that on top of it. The ender 3 pro's magnetic bed base is enough to keep the glass in place and the PEI sheet has adhesive on the bottom of it so I don't need to use the binder clips like I thought I would have to at first. It all just stays in place without shifting and I have access to the full print bed. The glass is still on there to correct a warp in the base bed and the PEI is honestly such an upgrade from glass. Things stick with no effort and come off easily at the end, except PETG which sticks like nobody's business and is harder to remove.

Buy

($6)Wires:For the MOFSET mod

($1o)MOFSET

($6)Wire spades:For the MOFSET mod

($8)Assorted M3 Bolts:You need some for a few mods and for the bolts you will inevitably strip on this cheap wonderful machine

($13)Longer assorted M3 Bolts:For a few mods

($9)M4 Bolts:For one of the mods

($9)Metric allen wrench set:Had to order one of these since metric tools aren’t common round these parts

(~$20) PLA of preferred choice- You’ll run out of the sample bit quick so go ahead and order a roll or two to be prepared. You will note some upgrades require ABS so a small spool of that to your order will also help.

($6)M3 Lock nuts:Critically needed for a simple mod

($10)Threaded rod and nuts:Please note that this item seemed difficult to find online. I recommend going to your local hardware store and getting two 5/16” rods of at least 16” in length. They should have an assortment of threaded rod in various lengths available. Also note that the pitch of the threading matches the nuts you buy. Further instructions regarding this can be seen in Azza’s Z-Axis braces below.)

($6)9mm Wrench for the nozzle: Don’t wait for your first clog, go ahead and have this on hand to remove/change the nozzle. Note to only tighten/loosen the nozzle when heated.



Below is the order of printable upgrades I recommend but I suggest you mix in a few other prints along the way because this is a hobby after all and you should be having fun. It helps to have your quality as tuned in as much as possible for some of these so be patient and keep trying if you need to.

Print

Spool holder- temporary : Until you can mount your spool on top of the enclosure or any other personal preference.

Belt tensioner- print x2

Z-brace

Shielded stop button

Cable relocator : It’s a pain, but if you spend the time to do this and turn your extruder motor 90 degrees then you can get the full Z height without ruining your cables. It does involve opening all the cables to the PSU and feeding a few extra inches back through the cable chains.

Cable shroud : Looks nice if you do the cable relocator.


The following need to be printed in ABS:

M3 Bed Nut retainer: 10/10 upgrade. I know they look worse than the nice metal stock ones, but these help keep your bed level longer.

CiiCooler

Glass bed Holder


Now that the first major round of printed upgrades is done it’s time to shift to a few more supplies to pick up to really fine tune the machine.


Buy

($5)Radial fan: For CiiCooler

($5)Glue sticksThis and a glass bed is magic

($25)Borosilicate glass 8” x 8”

($26)Y-Carriage plate upgrade: This has been a nice upgrade as I now only need to relevel the bed every couple weeks instead of every print. Check out this guide for a ‘how to’ as well as a free upgrade by shifting your Y pulley over.

($15)rechargeable dehumidifier: For keeping in the bin with your opened filaments

($9)Extruder gears: Might be able to hold off on these, but will need eventually. If for some reason you have a Maker Select with metal X-axis blocks (V1 and V2, but not V2.1) then this is a must. You can follow this guide for a how to.

($28)Metal extruder plate and lever: Not needed, but nice.

($14)Noctua 40mm fan: Not needed, but makes the printer a lot quitter. A LOT quieter.

($50)MicroSwiss All Metal Hot End: The destruction of my PTFE tube by this point pushed me to doing this upgrade. If needed you can follow this guide for replacement. Remember to tighten/loosen when the nozzle its hot.

($6)Ceramic cotton: Tore off the stock one when replacing for the all metal hot end by accident. At least its thicker than stock

Now that the printer is in its final form, its time for the enclosure which is a stacked Ikea Lack hack.

Print

Spool holder

Pi Case

120mm fan cover

Fan grill

120mm fan PSU modification: I edited this to fit upside down since my PSU is mounted on the underside. This was nice since I blew the 40mm fan anyways so it made everything a lot quieter than before.

IKEA Lack filament guide

Webcam holder: This is one I designed specifically for the webcam I happen to have lying around. The camera mount piece can be changed out no problem though for what ever webcam you have or buy. The SketchUp file is included on Thingiverse for such purpose.

Buy

($20)2x Ikea Lack: Luckily there is one right down the street from me. I am located in North America though, so we do not have the STUVA, if you live literally anywhere else you may check in to this as an alternative.

($80)Plexi glass for enclosure: Could be cheaper alternatives, but it looks cool

($9)Foam pads for feet

($42)Raspberry Pi3: For OctoPrint. I also suggest using a different USB cable than the stock one provided by Monoprice or you will have issues.

I ended up ordering a generic borosilicate glass bed and applied some GizmoDorks PEI to the top of it. Works excellent and I don't need to use any painters tape or glue stick with it. It was a great upgrade from stock and much easier to level. Haven't decided yet if I want to dump my dial indicator leveling for a BLTouch or equivalent. I might end up doing that though.

Directly. Creality 3D Printer Platform Heated Bed Build Surface Tempered Glass Plate for Ender 3/Ender 3 Pro 3D Printer 235x235x3mm https://www.amazon.com/dp/B07FSM8DK9/ref=cm_sw_r_cp_tai_s9RvDbM16RZ7Y is the one I got. It has a coating on it. I have been extremely happy, though it took me another 15 minutes to relieved since it’s thicker and you gotta reset everything.

Only real change is you should wait for it to cool before pulling stuff off, but once it cools, it doesn’t stick. Like... at all. It’s quite nice. Also, it doesn’t warp, which I only found out after, because I was only after a new bed and figured I’d upgrade. Then I read about it ;)

Do you mean the little blue clips? They've been coming with those for a number of months, but yeah, do yourself a favor and just get some better quality pieces to begin with. This is what I'm using, as an example.

Thanks for the detailed reply.

​

I need to read more to understand the z switch and z screws you are referring to. I have no idea what those are. I assembled by watching some channel on youtube do it. It was like a tales from the crypt vibe channel.

​

As much as it sucks, I probably need to completely disassemble it and start over. There has to be something done incorrectly for it to be this difficult. I am definitely going to get one of those gauges before I get back into. I returned the springs today and ordered different springs on amazon. When they get here, I might sit down one night and try again.

​

As for the bed, the glass one I got was scratched to hell from those stupid springs. I didn't know I had to raise or lower whatever switch you were talking about. Like I said earlier, I already ordered a SD card reader so that will be a definite mod. As for the octopi, is there a list somewhere on this subreddit of everything you need to purchase before starting? I have a raspberry pi at the house. I originally bought it to build a retropie but I haven't gotten around to it yet. I could use it for the printer if needed. I really like the idea of remote printing, having a webcam to see the print live, and putting a part on there that stops the print if there is a filament issue.

​

I have to go into the city tomorrow so I was thinking of stopping by ikea and getting some Lack Tables for the eventual enclosure but now I don't know if I am even going to keep the Ender 3. I am debating on returning it and moving up a tier. I really want to get started on this but it seems like I am never going to be able to print any of this awesome stuff. So many awesome files on thingiverse and I can't use any of them.....

​

Here are the parts I have purchased so far....

Metal Extruder Upgrade

​

Filament Black and Red

Looks like you have a clog in your nozzle. Happened to me recently and i had to end up swapping the whole thing out.

Do your self a favor and grab one of these: http://www.amazon.com/Hotend-Nozzle-WANHAO-FlashForge-Builder/dp/B01C3HEQZC/

Its an all-metal hot end upgrade that is all sorts of better than what came stock on your printer and really easy to install. It will also fix the issue you're having right now.

Otherwise you need to figure out a way to get what ever is clogging your print head and causing you to under extrude out.

My advice (first of all) is to install ADVi3++ if you haven't, the bed-leveing function (under the Tuning menu I think) is pretty good.

Some general advice for the actual leveling process:

• Start with the knobs tightened enough that the nozzle is too high everywhere and work from there.
  
• Underturn each knob during the leveling process. Loosening the knobs adjacent to a corner you're leveling will affect that corner somewhat - e.g., loosening the front left and back right knobs will also lower the bed for the front right corner, so if you adjust the front right corner knob fully, when you loosen the other knobs, the bed will be too close in that corner.
  
• Keep making minor adjustments, keeping in mind which corners are high/low, until a piece of paper can be slid under the nozzle with some friction.
  
  If things still aren't leveling:
  
  
• Mess with your z-axis motors. I actually just used a normal level for this, which worked for me, but you may require more experimentation.
  
• Adjust your z-endstop. Especially if you've put a glass bed in place, you may have set your endstop too high or too low to effectively level the bed. Ideally, you want the knobs to be about in the middle of their range while the bed is level. If the knobs are too tight or too loose, wonky things can happen (bed can get pulled sideways slightly)
  
• If all else fails, you probably have a warped y-carriage. Mine is warped slightly, and leveling is harder for me than it should be. You can get a replacement y-carriage here, and you can follow this video to replace it.
  
  Once you can actually get things level, I highly recommend getting some M3 nyloc nuts and replacing the default bed leveling knobs with these. They don't look as nice as the metal/stock ones, but it will prevent vibration/movement from de-leveling your bed as quickly.
  
  Good luck!

It's a super easy mod to do. The parts are like $8 on Amazon and you print the mount. This is the first thing I did on my Maker Select.
Mod link: https://letsprint3d.net/2017/01/29/guide-installing-a-mosfet-board-maker-select-v2/
Part: https://www.amazon.com/dp/B01HEQVQAK/ref=cm_sw_r_cp_apa_i_cZbPCbG4PRAN7

Important thing to remember: Nothing is -ever- mandatory unless it's a major safety issue. The closest thing to that on that printer is the mosfet. I believe your original message implies you replaced the buildtak, so the Mosfet upgrade would be a very good idea unless you plan to change out the control board entirely.

Everything else is Optional and Quality of Life/Print stuff. ^.^

The following are examples on Amazon. Other folks and posts may have better advice on where/what to get.

Y Carriage plate
https://www.amazon.com/dp/B01MUAMRN7/ (This is the part under the heated bed)

MicroSwiss all metal hotend (From other person's post):
https://www.amazon.com/dp/B01E1HANLS/

Linear bearings would be LM8LUU for the Y rods. If you have the plastic bearing holders, it's easy. If you have the aluminum block bearing holders, you'll have to find somebody else to source info on the circlips and how to not become sad with them.

You can print things just fine without any of these upgrades, so don't worry about the long print (unless you run out of filament).

A new controller board can do extra stuff and is required (Highly recommended, since you "can" make the probe work on the Melzi board, but poorly and at the cost of other things) for Z-Probe use, dual extruder, and with the heated bed on that printer, can remove the need for a separate MOSFET. It opens the path for other upgrades, can improve print quality to a degree in some cases, and can drive you absolutely nuts trying to set it up.

The inexpensive Quality of Life I'd recommend are thumbwheels with nylock nuts (hard to turn, but keep your level for a long time); corner-bracket spring cups (printed); and glass print bed. Two sets of printed things and about $12 at worst for the glass.

The bearing upgrade (If you can do it without fighting circlips) helps reduce Y-axis stutter and vibration. That upgrade brought my print quality up hugely. $25 or so if you get a lot of spares or higher quality ones.

The Y platform helps you with leveling and staying level.

The lack enclosure has some printed parts, $20-40 worth of Ikea furniture, and up to $50 worth of siding depending on your ability to cut glass and plexiglass.

So many things you CAN do. None that you MUST do. Some that you SHOULD do. And everything else is Just For Fun.

If you get the entire upgraded hotend from Micro Swiss it will allow you to print with more abrasive filaments, like color changing, exotic infused filaments (ie. carbon fiber, bronze, wood) and at higher temps which is needed for things like PETG.

The glass plate makes sure you get a flat surface since the build plates are usually not 100% flat.

With that being said, buy the Maker Select printer from monoprice then head over to amazon and get the micro swiss hotend from there along with the boro glass plate. Total price will be around $441 with shipping of everything.

Yeah, maybe my post wasn't clear.

Printer board is an MKS Gen 1.4: https://reprap.org/wiki/File:MksGenV14-Pinout.png

Mosfet board is one of those cheap things from Amazon: https://www.amazon.com/BIQU-Power-Module-Expansion-Printer/dp/B01HEQVQAK

This is a DIY printer that started life as an Anet A8, but now is a mix between an AM8 mod (bed and frame) and a Prusa MK3S clone (extruder), all running Klipper and Octoprint.

Currently this external Mosfet is controlled by D7 (the onboard Mosfet output for the second extruder) and powers the bed. The hotend is on D8 (because its Mosfet is a bit beefier), the extruder fan is on D9 and the print fan is on D10.
Filament sensor and BLTouch are on D10 and D6.

I'd like to use D7 to power an enclosure fan, but to do this I need to control the external Mosfet from a different pin, ideally D4 or D5 (which are marked as "servo" pins on the pinout diagram). I've tried various other pins and combinations with +5V and GND and various resistors in between, but I can't get the Mosfet to switch.

Hey Omnioji,

I am a big fan of yours, would love to help, but some more info would be needed.

I know you say FDG profile, but some things in those profiles are also kinda fluid and need to be adjusted by you. So in particular, what is your print temperature? What are your retraction settings?

One simple fix which would likely give you some improvement would be to upgrade your bowden tube to a smoother PTFE Tube which causes less friction on the filament and therefor reduces stringing.

I've had good results with the standard .4 nozzle. As long as it prints clean, I've had more success putting effort into post-processing. This stuff does wonders for painting. I've printed minis on .5 and .6 nozzles with similar results in quality.

Here's the aluminum extruder assembly. The plastic one that comes on the printer WILL break. It's just a matter of time. They crack from stress after a while and even before that they creep and you'll start getting missed extrusion.

Here's the stiffer bed springs. You won't have to compress these as much to get a good stiffness.

Another really popular upgrade is this glass build plate. It has a special coating that makes it so parts stick without adhesive, and it leaves a really smooth surface on your prints. Parts stick really well then when it cools down they self-release.

The 3 upgrades I linked are extremely popular upgrades. You can get by without the glass bed, it's just an option because the stock bed will wear out eventually.

Nice! I'm sure that'll look awesome. I suggest using bondo to fill cracks and divits and XTC-3D or a similar epoxy to cover the entire piece to smooth it out.

This is the one that I got: Title of link (optional) I got a metal extruder housing as well but I honestly don't think it's necessary, just nifty.

My best results have been prints in clear resin, but "transparent" PLA can be enhanced as well.

I bought the following:

https://www.amazon.com/gp/product/B00PFXK4JY

You mix it like epoxy, and lightly coat the outside. I use my hands (with gloves). It removes minor blemishes, and makes for a "smoother, shinier" part.

It is not for everyone; sometimes I prefer the "frosted" look on a part.

PRO TIP: Buy a box of thumb tacks. Put a bunch of them point up so your part can dry without sticking to anything.

I just have the Creality glass bed from amazon https://www.amazon.com/gp/product/B07FSM8DK9/

It's been fantastic. Assuming your bed is properly leveled you don't even need to use adhesive, just make sure to clean it every once in awhile.

There are ways to make it cheaper.

A MOSFET (basically a relay that switches the circuit for the heated bed) would be a huge upgrade.

You can flash the firmware of the board with proper security measures in place. Lookup Marlin firmware.

That would be your number one tasks and a huge safety upgrade.

There are lots of tutorials on how to do both.

I'm pretty sure I just got an official creality one, but here is an Amazon link. I'm glad you got it figured out!

210-215 so far. The printer auto heated to 215, then I tried at 210 since that's what the Hatchbox directions said. Is this the hotend? I actually already purchased this but didn't install it yet. So I should purchase this as well? Thanks so much for the help!

You can just replace the gear, but this is cheaper and better if you haven’t upgraded yet, or get them both 😁

I'll start with the non-printable mods:

Replaced the PSU with a 750w ATX PSU I had lying around.
If you do this, you will more than likely need to add a power resistor to the 5v rail. I also removed all the original wires and connectors from the PSU and resoldered just what I needed with better rated wire.

Glass bed on top of the aluminum. I just went to Lowes and got them to cut a few pieces of single pane glass.

Firmware:
To get the sensor working, you'll have to change the firmware unless you only want to use it as a limit switch. The only option that i'm aware of is Skynet which is based on Marlin and works fairly well. You can find that on their facebook page: https://www.facebook.com/skynet3ddevelopment/

Blue LED Extruder Fan (because the original broke). I don't remember where I got this from. I'd like to find an RGB one! ha

I added a bunch of WS2812 LEDs controlled by an Arduino at the moment, I am using OctoPi so eventually i'll have that control them but at this point they're set to UV colors because it looks cool.

Anti-Z Wobble I modified this but no longer have the file, I also printed a cylinder to wedge into the hole above the lead screws.

Bearings I used:
https://www.amazon.com/Beerings-Malt-ABEC-Skateboard-Bearings/dp/B005NFXHQG/ref=sr_1_2?ie=UTF8&qid=1493094188&sr=8-2&keywords=beerings

Belt Tentioners I can't remember which ones I finally used.

I think this is everything. If I remember something else i'll post it.

I totally recommend the All-Metal extruder Hotend for the i3 as well, once I threw that on, my prints were beautiful.

https://www.amazon.com/gp/product/B01E1HANLS/

I'm working on this mod: https://gigdigit.com/extended-heat-bed-kits-120-x-250mm-print-area-3mm-thick-select-mini-v1-v2/

The double-sized hotbed takes more power than the stock power supply can put out (especially the newer 7 amp models, which I have)

So I decided to use one of the MOSFET drivers, through the existing power jack, to which I'll connect a beefier power supply. I chose this one: https://www.amazon.com/gp/product/B01HEQVQAK

The top two terminals tap into power as shown here: https://imgur.com/NYOGok9

The bottom two run through the braided cable (joined by the thermistor wires and run to the new platform. The small connector goes to the original board's hotbed connection.

If anyone else has done this mod, or something similar, I have a few questions.

1. I can't quite figure out how the hotbed wires are supposed to route. The larger bed has connections on the side. Facing the printer, would those work better attaching at the right-hand or left-hand side? (I can post pictures if it would help)
   
   
2. I had previously done the external wire routing for the hotbed. Is externally-routed wiring advisable (or even possible) with this configuration?
   
   I'll probably have more questions as I go. :-)

I ordered this one, and it got to me in Canada pretty quick for a decent price: https://www.amazon.com/gp/product/B07B251KBS/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

I've literally only done two prints since I got it installed though, so I can't say how big an improvement it is on the original yet.

I am also interested in changing the bearings on the y axis and the x axis. Are these good bearings to make the printer quieter and maybe more stable?

https://www.amazon.com/Printer-Solid-Polymer-LM8UU-Bearing/dp/B06XPRCMJS/ref=cm_cr_arp_d_product_top?ie=UTF8

I've been using a sheet of PEI that works like a charm. The one i got was from amazon, something like this would work https://www.amazon.com/Gizmo-Dorks-Printer-Surface-Adhesive/dp/B074XLD5QH/ref=pd_sim_328_3?_encoding=UTF8&psc=1&refRID=PPGSHY9T4C0YC14V4FVS

It even comes with the adhesive.

The nozzle on that printer is a MK10 nozzle. There's a bunch on Amazon.

Unless you've been really abusive, it could just use a nice clean. I use a brass brush on mine. Just pre heat the hot end and scrub away. It'll be fairly clean when you're done.

But if you want to change the nozzle, you may want to go ahead and upgrade to an all metal setup with the Micro Swiss hot end. This comes with a new nozzle and some other stuff.

I personally have the Micro Swiss kit with their plated nozzle. After scrubbing it, it always looks good as new.

The PSU has a built-in fan that kicks on and off when the PSU gets warm. I don't plan on printing things with any crazy high temperatures, so these upgrades were probably a bit overkill, but I'd rather have components that are a bit more trustworthy than what comes with a $150 kit.

I found this metal replacement for $11 on amazon when I had this issue a few weeks ago, such great value

The e3d V6 lite needed this carriage mount (and this is the direct-drive version, not the bowden setup) to be printed in ABS (and ONLY ABS, PLA will warp and eventually bust. Plus, ABS repairs with acetone really well and easily, so I've busted the one I printed a while back a couple times and just re-welded it together). This is the power supply I got, and I also got two of these MOSFETs. More info on the wiring here, I'd also recommend their advice in replacing the wiring to the bed and the mainboard with higher-gauge wires to prevent issues.

Ninja edit:
I also had to adjust my printer firmware to have the new center-point for the hotend set to actual center, for that I had to flash SkyNet3D firmware, a Marlin-based firmware made specifically for the board the A8 came with. If you're replacing the board with a RAMPS board, more than likely you'll be setting it up for all that anyways.

These two things took my prints from adequate to pristine. Huge improvement.

It looks like the extruder arm may be squeaking the filament against the extruder wheel so tight it is causing skipped steps and filament to wear off on the wheel.

I bit the bullet and got an aluminum extruder arm kit from amazon - CHPOWER CR-10 Extruder Upgraded Replacement, https://www.amazon.com/dp/B079JZ374W/ref=cm_sw_r_cp_api_i_kCaPCbF0AF0C3 - and have had good luck and no more skipped steps since changing.

I’ve done some basic configuring on a pi before, but not an Arduino.

Is something like this a good place to start?

Yeah, a second external mosfet. One of these: https://www.amazon.com/TriGorilla-Printer-Heating-Controller-Extruder/dp/B01HCVJ3K2/ref=sr_1_19?ie=UTF8&qid=1526154992&sr=8-19&keywords=mosfet The MK2/S has had a history of having arching and melting in the plug they use to hook the heat bed to the RAMBO. That's why the MK3 uses screw terminals so its less necessary. They're much safer and more robust. The PSU has a spare empty 12V +/- terminal. So I desoldered the heatbed end. Ran those leads to the on/off signal input of the external mosfet. The RAMBO bed output now becomes a lower amperage enable/disable signal. Then I ran new power leads from the PSU to the power in on the mosfet then power out to the bed, soldering those new leads onto the bed. Printed a small enclosure and use some self adhesive velcro to stick it to my rambo case. Aint pretty, but the risk of a meltdown is greatly reduced. Probably overkill but better safe than sorry.

This is what I'm using and it's been fine for the past 6 months; glossy finish. I think what Prusa includes is closer to 7 mil though.

I'm sure there are some differences in heat transfer properties or something with regards to using a thinner sheet; but the only things I've noticed are that the screen printing can distort the surface slightly (visible dimple, but can't feel it) and I need to be more careful with my removal tools so I don't accidentally scratch through it and into the heat bed. I had been using a super sharp putty knife, but switched to this recently (basically a thin metal kitchen spatula, with rounded corners).

I've been working on converting to a ramps 1.4 kit. That's the one I ordered. I also picked up an ATX power supply so I can control it with my pi. As far as the conversion goes, it seems pretty simple, installing the Marlin firmware was weird (I ended up having to do the configuration/install myself with the current version of Marlin, not using osoyoo's custom one). I just printed the mount conversion and I'll be installing it soon.

Not sure if it helps or not, just wanted to give you my perspective :)

You can use xtc-3d from smooth on to get a super nice smooth finish, that's what I did here

It's multiples of 0.04, but it won't have a huge impact.

Regarding hair spray/glue stick etc... a PEI sheet will save you a lot of effort. You put it on top of the glass and then print directly on it, no need to do anything. Edit: and yes, as /u/PuterPro says, get your bed flat.

It really depends on how comfortable you feel with electronics. Watch Youtube videos on the conversion and see if its something you are up for. If it were me, I'd do RAMPS (still with the mosfet mod) with Marlin firmware. Several people on this sub have done it and would mostly likely be nice enough to give you their Marlin firmware. If you go this route you'll have to set the current limit on the drivers, edit the configuration.h in Marlin, calibrate the e-steps, PID tune both hotend/bed and give the RAMPS board solder joints a carefully once over. Sometimes there are extra solder balls and shotty joints.
EDIT: you might also need to recrimp some connectors.
