This is how the new stepper motors were mounted, to replace the servo motors. Two 16 tooth pulleys for a 1:1 ratio, since the Vexta NEMA11 motors have an 18:1 gear head which is sufficient gear reduction. One screw goes into the hole in a corner, and anther new hole was drilled and made a bit wider than the screw. This allowed the belt to be put then tensioned by pulling the motor away from the other pulley, then tightening the screw, which has a washer.
