Filament unload failed, "open idler and remove manually" message but I can't find instructions how?
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 better HOWTO I am unable to find for some reason? I cannot imagine I am the first person to receive this error message but for the first time with this printer I am absolutely unable to find a KB article or video or something.
RE:
hi, took the wrong road 😉
You don't have to open/disassemble the gear. Just open the Lever #1 upwards and than you can open the the idler. #2
That way you can pull out the filament manually. take a look from the side to check for debries on the gear. (try to blow it out ore use a toothpick or similar)
