ACME Screw

Thread the ACME screw into the ACME nut in the Z Sled. Twist the screw until the nut is about halfway down the length of the screw.

Use a shaft coupler to connect the shaft of the Z Axis Motor to the top end of the ACME screw. You may have to loosen the bolts on the Z Sled to get it to snap onto the Z Rails.

Z Sled Rails

Slide the Z Sled Rails through the arrow-shaped slots in the Z Cart Top. Push them until they are securely seated in the diamond-shaped indentation in the Z Cart Bottom. Add two Z Rail Spaces to the top and the bottom of the rail pair to fix in place.
