Open the extruder_idler

Insert a piece of 1.75 mm filament through the extruder_body into the PFTE tube.

Center the filament on the drive teeth carefully, using the Bondtech set screw.

Tighten the set screw. Don't tighten too much as you will damage the thread.

Remove the filament.

This is a good time to put a dab of lithium based grease on the gears. Make sure that you do not put any grease on the drive teeth.
