New Prusa Mini+ cannot unload filament
Hi all,
I’ve assembled my prusa mini+ and at first it was difficult to,load filament, but it finally did.
The first print appeared to work well after calibration, but then I started noticing extrusion errors.
I purged the filament and this seemed to work. I tried unloading the filament, but it will not unload.
I’ve removed the Bowden tube above the print head to confirm the filament has been removed from the hot end.
When I try to unload, the wheel spins, but squeaks. I tried assisting it by pulling on the filament, but it is stuck fast.
Has anybody got any ideas on how I can fix this?
RE: New Prusa Mini+ cannot unload filament
I fixed the issue, I undid the Bowden tube and loaded the filament to pushed it back in, I did this a few times and found that the new filament had a big chunk carved out of it. The filament was also snapped, I cut off the bad part and then the mini unloaded the filament.
im not going to try anything tonight until I can get a small hex key to fix the under extrusion issue.
