Locate the extruder motor so the wires face to the left. Rotate the shaft so that the flat side is facing up.

Mount the Bondtech pulley on the extruder motor shaft so that the geared portion is furthest from the motor body. Make sure that the set screw is in contact with the flat portion of the shaft.

The motor shaft should protrude from the pulley by approximately 1mm.

Secure the set screw to avoid the gear moving. We will fine tune the position later.

Verify the orientation of the motor cables.

Secure the extruder motor to the extruder_body using two M3x25 screws.
