Reddit mentions of Micro Swiss CNC Machined Lever for Wanhao i3 extruder

That link looks like a Bowden extruder setup where the stepper motor is further upstream from where the plastic is melted/extruded.

I have a MS+ also, the recommended replacement for that part is the MicroSwiss all metal hotend.

Here is the block:

Glad I could help. (Maybe? ;)

Good turning down the accelerations and jerk I had to do the same thing and it does help.

So for the glass bed, I bought [this one] (https://www.amazon.com/gp/product/B00QQ5Q3BI/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1) which has been excellent for me despite some of the bad reviews. I also bought this thermal pad. It has to come from china which is kinda a pain but it delivered pretty quickly and is HUGE compared to some of the other ones on amazon. That means I can use it for other projects and have replacement pads, which is nice.

Here's a great guide for this and for most things related to this printer

I also went ahead and upgraded to a Micro Swiss nozzle which has been a really nice upgrade for me. I also upgraded the filament feed lever because I like fancy aluminium replacement parts and the plastic one didn't seem like it was going to make it in the long run.

A note about shipping: They are FAST. I hit order and within fifteen minutes my order was out their door and on it's way.

The final thing I did was purchase a shim set. At my work, we do a LOT with 3D printing. We've found that using shims to set the nozzle exactly .2mm off the bed is the best way to get the printer to excel on the first layer. If you are confused on how to use the shims to achieve this, I can take a picture.

EDIT: When using the glass bed you're going to have use Elmers Disapearing Purple School Glue to get prints to stick. It's cheap and has been giving me excellent results. I may switch to Elmers Glue-All which we were using at work for Nylon prints and Gahddamn is that stuff great for nylon prints.

EDIT: RECALIBRATE YOUR ESTEP. This fixed a lot of my infill and layer problems because now my extruder is laying down the correct amount of filament.

Yes, my printer was working perfectly before, but I think I've found the problem:

I disassembled the lever and and extruder plate to see if there was something else I could clean or assess for damage. There were some globs of burnt plastic under the gear, but that wasn't the problem I found. The idler bearing was not moving. I took a piece of filament and inserted it between the gear and idler and let the lever down and manually pushed the filament through. I saw that the idler was not moving at all. however the extruder gear was gripping the filament well and turning like normal. I've ordered this microswiss drop in replacement for the lever. I also plan on printing this extruder plate to go along with the new lever, but that's besides the point. The new lever arrives tomorrow, so I'll keep you updated if it works or not.

Edit: You can also purchase a metal version of the extruder plate I linked, in case you're interested in it.

I did this one

I am already running this but have not yet recieved this
EDIT: I just saw the Microswiss extruder plate. I have not purchased that. If you have it, do you recommend it?
