Rotate the stepper motor to the position shown in the photo. This location will give you the most available range of motion for tightening the belts after they are installed.
Route the belt as shown in the diagram on step 16
Be sure that the belt is not routed on the outside of the frame or carriage pieces! This will prevent motion.
To thread the belt ends into the carriage, use a wire tie or the cut-off from a wire tie to guide the belt up into the belt slot.
After you have threaded the belt into the carriage pull the belt end tight - you want to pull all the slack out of the belt.
Install the second belt clamp
You can trim excess belt, but leave approximately 1" past the belt clip.
Complete the routing process for the remaining two towers.
