Ultimaker springy wheel
by yzorg, published
Wanted to have a extruder wheel that slightly gives a bit..
When thers a Pressure being built up in the filament drive, the cogwheel can jump a tooth and release that pressure.
less stress on the filament when retracting very fast and often.
maybe its good for difficult materials aswell.
i think of soft materials..
