Loud noise when unloading, doesn't unload

Just today the extruder motor started making this noise anytime it needs to go in reverse (unloading).

No visible jam inside the housing. (see video)

Since unload wasn't working I've managed to pull out the filament by force.

Since unloading the filament I've tried running a few "unload" commands and it even makes this noise without any filament at all, so I'm pretty certain it's not the sound of "grinding filament".

Any suggestions for other things to check would be great.

Hello, I have the same problem. Did you manage to fix it by any chance?

Greetings,

Michele

RE:

Nothing I've tried has completely fixed it. I disassembled the extruder, made sure all the parts were clear of debris, made sure all the gears could spin properly/interlocked properly, and put it back together... that helped some, but it still gets caught and makes noise when unloading filament.

It seems to stick on the very end of the filament when unloading. I generally just pull hard to get the final few inches of filament out. I hope I'm not damaging anything?

I may look into a different extruder at some point, if no better solution comes up. (I hear good things about the Bondtech ones?)

RE: Loud noise when unloading, doesn't unload

So, I contacted support and I've been sent the following parts:

  • MINI-Extruder-front
  • MINI-Extruder-rear
  • Extruder motor pinion

Swapping these parts and playing a bit with the positioning when tightening the screws fixed the problem for me. I hope this can help you too.
