Filament can't push through the feeder


Recommended Posts

Posted · Filament can't push through the feeder

Hi everybody, i have a strange problem:

this morning i was switching from a PLA to a ABS filament.

everything went fine till i removed the old filament and inserted the new one...

i pushed the filament a bit so the feeder could grab it and the feeder started pulling up the matirial...only to stop a few millimiters later

after trying several time, i noticed that after the filament is grabbed by the motor wheel it make a little turn and it miss the hole that lead to the bowden tube

the filament is straight and i tried with other filament but the problem remain

what could cause the filament to "turn" and how could i fix it?

Thanks in advance. :)

    If the filament is oversize then it may have trouble getting through the gap between the drive cog and the idler wheel (bearing). You would have to back off tension. If the filament has a tight curl then it's possibly just getting hung up somewhere.

    I would recommend a switch to Robert's feeder.

    ...or the variation on it which I actually use.

    Not only is it easier to tweak the tension on this feeder, it's also great for quick filament changes: you can manually poke the new filament into the bowden tube before closing the tension arm, so the problem you describe simply couldn't occur.
