Description
this is a WIP
i want to have a extruder wheel that slightly gives a bit..
When thers a Pressure being built up the cogwheel can jump some tooth and release that.
less stress on the filament when retracting very fast and often.
maybe its good for difficult materials aswell.
i think of soft materials..
different variants provided

Most of the stress on the filament is actually due to the default extruder on the ultimaker. If you upgrade to the one with the roller bearing, it puts a lot less stress on the entire machine. Just make sure you get the tension tight enough.

These wheels actually add some more softness to the acceleration of the extruder movements.
