MMU NOT LOADING FILAMENT
Hi,
My MMU3 is not loading the filament. I can hear the motors turning and the idler lines up but the filament will not catch on even if the idler is tightened all the way. My MMU has worked before for the past three months and I don't know why it stopped working now! Please give me your thoughts.

RE: MMU NOT LOADING FILAMENT
The idler MUST NOT be tightened all of the way
See Step 38 at this link - https://help.prusa3d.com/guide/6-pulley-body-assembly_328918
when loading you need to feed the filament into the MMU until it is grabbed by the pulley wheel... sometimes there is a bit of a restriction at the MMU End of the Feed PTFE Tubes. cutting the filament end on a slope usually helps get past this.

Hi Joan,
My idler is tightened just like in the instructions and I even adjusted it a few times but still no luck.

can you manually load the filaments to the front of the MMU3 (behind thefilament cutter section, with the idler cover open?) then close the idler cover, and try a print?
