Worm instead of hobbed bolt for extruder

Recommended Posts

Posted · Worm instead of hobbed bolt for extruder

I don't know if anyone has tried it but my gut reaction says that twisting of the filament would be a huge issue.


People that tried this confirmed this a few years ago.

    The BfB Touch and Rapman printers have(had?) wormgear extruders. They have good grip on the filament, but I thik I have read that they are not good with retractions, and "eat" filament and leaves a lot of dust.
