Unload Filament Failure
I have an MK4 with MMU3. I had a filament loading issue that began yesterday. I took the extruder gears out and gave them a good cleaning. This solve the loading issue, but now I cannot UNload the filament.
When I do the MMU3's load test, the filament loads just fine but consistently gets stuck in the extruder and so will not unload. I've tried to use the Unload Filament function but it also fails. With each, I end up with the stuck filament message.
When I manually unload the filament, I have to use considerable force (even after opening the swivel assembly)...much more than expected.
I'm not sure where to go from here. Any suggestions would be appreciated.
RE: Unload Filament Failure
After staring at filament load test after test, it would appear that the idler is not disengaging enough...or re-engages before the filament is unloaded. I might get one filament to work briefly, but all others error out. Then the good filament will begin to error out.
