loosen the screws on the Driven Pulley to increase or decrease the tension.

position of the Steel Belt on the Driven Pulley as you
move the carriage back and forth by hand. The Steel
Belt should be in the center of the pulley and must not
slide/drift to one side or the other. If the Belt drifts to
one side loosen the screw on that side a quarter turn
(or tighten the screw on the opposite side a quarter
turn). Test the drift again by manually moving the
carriage. When satisfied the drift is almost completely
gone, test the tension again.
