Mounting Instructions
To mount the motor, start by turning the leadscrew until the coupling set screw lines up
with the access hole in the mount. Carefully insert the motor shaft into the coupling. With the anges touching, rotate the stepper motor until the at on the shaft is in alignment with the coupling set screw. Tighten the set screw. Rotate the motor to align with the motor with the 8-32 tapped holes. We usually attach the motor using three screws and use a zip tie in the fourth hole to secure the wire bundle. If you decide to use LocTite® on the shaft set screw, a problem can occur if the motor has to be removed. What can happen is the shaft ends up glued to the coupling. If this occurs, loosen the preload nut until the motor and shaft can be backed out to expose the coupling so you can work on it. Be careful not to ex the coupling or it can break at the dampening slots.
If using a non-Sherline stepper motor, make sure to grind flats on the shafts as shown where the coupling and handwheel set screws contact the shaft.
