FIGURE 5.20 Mounted coupler and the z -axis threaded rod.
Release the x -axis back onto the nuts as shown in Figure 5.21 . Use three small zip ties to
tie the x -axis stage to the three bearings. Next, mount the pulley to the x -axis stepper motor
with M3 trap nuts and M3 × 10 grub screws and mount the motor with three M3 × 10 screws
