For this section you’ll need:

• Z Cart Panels
  • (1) Z Cart Back
  • (1) Z Cart Front
  • (1) Z Cart Bottom
  • (1) Z Cart Top
  • (2) Interior Z Cart Rail Runner
  • (2) Exterior Z Cart Rail Runner
  • (2) Z Cart Spacer
• Z Sled Panels
  • (1) Z Nut Trap
  • (2) Z Rail Runner
  • (1) Z Sled Spacer
  • (1) Z Sled Face
  • (2) Tool Holder
• (~50) 8mm bolts, washers and nuts
• (16) Skate bearings
• (2) Stepper motors
• (1) ~8.5″/215mm length of ACME rod
• (1) ACME nut
• (2) Bushings
• (2) ~9″/230mm length of 1/4″/6mm diameter steel rod
• (2) ~28 3/4″/730mm-long sections of aluminum angle (3/4″ or 19mm leg length)

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.

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.

Attach the Z Cart Front.

Attach the Exterior Z Cart Rail Runners.

Attach the Interior Z Cart Rail Runners.

Bolt the Z Cart Bottom to the Z Cart Back.

• Bolt a belt pulley to the front spindle of one of your stepper motors. This motor will ultimately drive your X axis.
• Bolt the motor to the Z Cart Back (the one with holes in the face).
• Add two belt tensioners (as originally described in the Y axis section).

Bolt the Z Sled Face panel to the Z Sled Rail Runner assembly. Don’t forget to apply ironic sticker.
