  1. Compress the anti-backlash nut and thread it onto the leadscrew. Once the threads are fully through the nut, release the tension on the spring.
    • Compress the anti-backlash nut and thread it onto the leadscrew. Once the threads are fully through the nut, release the tension on the spring.

    • Thread the nut half way up the leadscrew.

  2. Using (4) M3 x 10 socket head screws and (4) M3 washers attach the stepper motor to the base.
    • Using (4) M3 x 10 socket head screws and (4) M3 washers attach the stepper motor to the base.

    • For easy cable management later, point the cable plugs toward the rear of the machine.

    • If your Z towers are still loose, make sure they are centered over the mounting holes for the stepper motors before installing the motors.

  3. Slide the small side of the coupler on the stepper shaft and tighten the set screw on the bottom half. Raise the Z yoke and slide the leadscrew up through the yoke.
    • Slide the small side of the coupler on the stepper shaft and tighten the set screw on the bottom half.

    • Raise the Z yoke and slide the leadscrew up through the yoke.

    • Set the leadscrew in the top half of the coupler and tighten the set screw.

    • Slide the yoke half way down the Z tower so it is flush with the top of the anti-backlash nut.

  4. Using (4) M3 x 10 socket head screws, attach the Z Yokes to the anti-backlash nuts.
    • Using (4) M3 x 10 socket head screws, attach the Z Yokes to the anti-backlash nuts.

    • If your Z towers are still loose, or not aligned with the leadscrew, now is the time to align and tighten them.

    • Turn the coupler by hand to make sure the yoke move freely.

    • Be careful when tightening the screw attaching the yokes to the anti-backlash nuts. POM will easily strip if you are not careful.
