1. Unscrew the mounting screws of both pulley housings.
2. Remove both pulley housings.
3.
Move the Y-axis and slide to the middle of the base profile.
4. Insert the toothed belt into the first pulley housing with the teeth facing the
pinion.
5. Feed the toothed belt past the guide pulley into the Y-axis and push it
through the Y-axis.
6. Feed the toothed belt past the second guide pulley on the Y-axis and push it
into the second pulley housing.
The overhang of the toothed belt from the pulley housings should be roughly
equal on both sides.
7. Push the toothed belt through both motor pulley housings.
To help check the clamping area of the toothed belt, mark the toothed belt
on the rear after the seventh tooth with a white pen. That is the only way
to check that the toothed belt is pressed far enough onto the milled tooth
profile on the slide.
8. Mark both ends of the toothed belt with a white pen as an assembly aid.
9. Pass the toothed belt through the guide pulleys of the Y-axis and feed both
ends of the toothed belt through the Y-axis.
