My new forgiving Wheels

[yzorg 9]

Hi guys

i came up with the idea of the extruder wheel that slightly gives a bit..

Idea: If thers a too high pressure being built up the cogwheel can jump a tooth and release it.

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

I intend less stress on the filament when retracting very fast and often.

maybe its also good for difficult materials aswell... think of soft materials.

Please test and critizise:

Thanks

have fun testing.

the one with the curved spokes is quite soft... you will have skipping teeth.

the other one is stronger.
