Reddit mentions of Capricorn Bowden Tubing Cutter (M-Bowden-Cutter)

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:

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:

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
