For this section you’ll need:

• X Rail Panels
• 5mm bolts, washers and nuts
• 8mm bolts, washers and nuts
• 1 Stepper motor
• 2 shaft couplers, 2 belt pulleys
• Drill rod, aluminum angle
• Timing belt

Pass the timing belt through the Belt Slot in the front left Vertical Brace. Continue to pull the belt until you can pass it first around the belt tensioner, then around the pulley, and finally through the Belt Slot at back rear. Fix in place with a pair of Belt Clamp Panels. Cut the pulley to length, leaving yourself a little extra on either end for adjustment. The biming belt should be somewhat taught and equally tight on both sides. Experiment to find the right setting for your rig. Once the belt is taught, fix pulleys in place on drive rod.

Repeat these steps for both the right-hand Shoulder Block and the Z Cart.

Insert a length of 1/4″ rod in the Exterior Panel of the left-hand Shoulder Block and push until about 1″ | 50mm is exposed at the Interior Panel. Now pass the rod through a belt pulley, then continue to push until the rod makes contact with the motor spindle. Fix the rod in place with a coupler, but let the pulley float for now.

Repeat these steps for the right-hand Shoulder Block.

Pass the rails/motor through the center of the Z Cart. Continue to push until the rails bridge both left and right Shoulder Blocks. Add four X Rail Spacers, and fix in place with 8 bolt/nut combos.

Bolt the remaining stepper motor to the X Rail Motor Mount with 5mm hardware.

Insert two Aluminum X Rails through the Exterior Panel of the left-hand Shoulder Block, and continue to push until about 12″ | 300mm protrudes from the Interior Panel. Now push the X Motor Assembly between the rails as shown.
