UM2 material feeder removal

Recommended Posts

Posted · UM2 material feeder removal

Hi guys,

I had to remove the cover off my material feeder to un jam my PLA. The reverse function wouldn't grab it, just kept spinning / grinding.

Tthe cover came off easily enough, but it seems the screws holding the cover on, also hold the feeder motor in place! so, now the motor is loose, and I can't get my hands in there to line it back up to put the screws and cover back in.

Seems like a bit of a silly design, as ultimately, at some point, you'll need to remove the feeder cover.

Anyone had this issue?

I finally managed to put it back together. Still though, I don't understand why things like motors are mounted with the same screws that hold cover panels in place.

Actually this is a good design decision. Thanks too this decision the center of the motor is always well alligned for good extrusion.

I also had some challenge getting the motor back in the right place after I had too refix the grindwheel since it has come loose.

A bit of challenge is not always that bad, and not having too many holes in the cover and integrating different functionalities into one screw is something good I think.

You could always take the rear left servo motor cover off. And you can leave it off if you want. I suspect it's only to make things look pretty.

I have a feeling, it's the same story there... cover screws also holding the servo motor in place? I didnt want to half dissasemble a brand new printer for the sake of removing some stuck filament.
