Unload from nozzle failures
My MMU3 is performing better, but I'm still having one problem.
From time to time, the filament fails to unload from the extruder. When I take things apart, the problem is that there's a little knob at the end of the filament that doesn't let it retract out of the extruder. I suspect temperature may be the issue. I'm printing with PLA, and my normal configuration is 215C for the first layer, 205C thereafter. I attached the 3mf file of one that failed, in case there are other parms of interest.
Any recommendations?
