I am assembling the MK9 according to pages 26-28 of the version 1.3 manual. The manual says to set the gear 9.5 mm down the shaft and tighten the set screw against the flat part of the motor shaft. When I do this it puts the screw past the flat part of the shaft and when I look at the filament grove alignment with the gear it is not close to being centered on the gear.
If I turn the gear over so the set screw is on top I can center the filament grove wheel with the center of the gear.
Am I missing something here?
