Hi All! I hereby want to introduce you to the Ingenuity Extruder, designed for the smart effector.

It’s a direct drive extruder which features a hollow-shaft Nema-14 stepper motor, Bondtech LGX drive gear, an eccentric breach which is self-locking, an idler wheel where the spokes act as a tensioning spring and a hypoid bevel gear pair, archiving a gear ratio of 1:6.5

The whole mechanism features only 4 moving parts: two gears, the idler wheel and the breach-lever
