Locate the 3/16” Allen belt tensioner screw that’s located on the right bottom side of the lower rail and marked with a red dot. Loosen this screw one turn only so that there is some movement in the belt tensioner.

WARNING: Make sure you do not over-loosen this screw. One full turn is usually sufficient. | Image Modified |
Locate the belt tensioner hole on the end of the belt tensioner. Place the 5/32” Allen screw and washer we removed from the lower gantry plate into the belt tensioner hole. Tighten the Allen screw until belt tensioner is flush with the rail and the springs are not visible.
