Note: Turn the printer off before you begin
Pull the bed all the way forwards to gain access. Blow compressed air in and around this area to clear any debris.
Here is a video to assist with the process:
1. Unplug the white cord from the motor so you can unscrew it and take it out of it’s housing.
2. Once the motor is removed, unscrew the small screws (circled in blue).
3. Apply blue loctite on each of the small grub screws. Then, start by tightening one of them down almost all the way on the FLAT face of the drive shaft (see the blue arrow pointing to the flat surface above).
4. Next, fully tighten the second grub screw down against the rounded section of the drive shaft, and then finish fully tightening the first grub screw against the flat face.
5. Reassemble the motor, and let us know when you're ready for a test print.
6. The problem is that the screw might have slipped and is no longer tight against the center of the flat surface.
