Filament unload failed,
My core one just failed to unload filament at the end of a spool (Prusament PLA), and is giving me the error message above. This message led to absolutely no useful instructions that I could find (multiple googling attempts with various keyword combos, etc) but eventually I got this page:
https://help.prusa3d.com/article/nextruder-filament-sensor-core-one-mk4-s-mk3-9-s-xl_465702
These instructions (step 3) said to "start by removing the PG case", and after taking the screws out I am stuck because I cannot pull the unit off. Looking at it closely it seems that the planetary gears are c-clipped on and now that I am unable to reassemble this easily (the screws will not go back in) I decided to stop before I make the mess worse.
Is there a re
