5 – Installing the Stepper Motors to the Motor Mounts
5.1 – The stepper motors are installed using four M3, 10mm pan head screws. I would
recommend using #4 star lock washers for extra peace of mind, but these are not included in the kit.
5.2 - Be very careful not to over-tighten the screws as you can easily strip out the holes on the
stepper motors.
5.3 - There are access holes directly across from each of the four stepper motor mounting holes
– they are there to allow you to install the screws on each motor. A longer than normal screwdriver may
help here.
5.4 - At this point you’ll want to install the belt pulley on each motor if you haven’t done so
already. Make sure that when you install the pulley, it’s positioned with the teeth aligned in the center
of the space as show in Fig. 22.
