Note the orientation of these components. In particular, the connector on the NEMA 17 motor.

Fix the coupling mount to the Motor face.

M3 x 16mm bolt

Slide the drive gear onto the motor's shaft.

Secure the grub screw against the flat of the shaft.

Align the gear so that the teeth line up with the path of the filament.
