It is important for the belt to be evenly spaced from the tower for its entire length. The red highlighted area in the first photo should help visualize what you are trying to achieve.

You will probably have to adjust the pulley position on the stepper motor shaft to align the belt evenly from the tower. If so, the next indented step explains how.

Loosen the two set screws on the pulley - you can see the set screws in the second photo. Then move the pulley on the shaft to bring the belt into alignment with the tower.

Tighten both set screws once the belt is properly aligned.

Repeat Steps 42 to 44 to install the belts on the remaining two towers.
