6. Take the limit switch and position it on the
same side as the stepper motor. Use two
M3x16mm screws and insert them through
the motor/right/middle and finish them off
with two M3 Nylock.
7. Slide the 5mm bore pulley onto the shaft of
the stepper motor. Secure it in place by
tightening the two set screws on the pulley.
8. Place the idler (2 bolt) on top of the 500mm
2020 beam and hold the idler pulley in
between the two holes. The idler should be
strait up and down. Lock the two T-nuts and
secure the mount in place.
