3.1 – When installing the pulley, make sure you do NOT over-tighten the screws. The belt pulley
is made from aluminum and can be stripped out easily. Tighten both screws equally.

3.2 - Note that if the set screws in your kit are as large as those shown in Fig. 19, you’ll need to
install the pulley after you’ve installed the stepper motor in the motor mount. The set screws won’t
clear the opening in the motor mount.
