Step 9: Mount Z Carriage

Step 1 Mounting the Z Carriage

There is not a lot to this set of steps but it can take some patience because the angles involved can be tricky.

Sit the Z carriage into the X carriage as shown and align the threaded rod so that it is centered in the large motor clearance hole.

Take the shortest rods (again make sure to wipe them down thoroughly with paper towel) and insert them from the top down. Lightly dampening the rods with a moist paper towel after cleaning can make them much easier to slide down through the rubber bushings.

Slide down through the X carriage top and into the liner bearings of the Z carriage. Continue pushing them down firmly but carefully through the bottom of the Z carriage and finally into the bottom bushings on the X.

Mount the motor in the same fashion as you did on the X carriage. Note that ONLY 2 screws are used to mount the motor at the top of the X carriage. There are 4 holes but 2 will not be accessible. Two holes are used to permit some thermal cycling of the acrylic if the machine is left idle for long periods.
