1. Screw the actuator onto the large panel.
2. Attach the small panel to the laser holder (this holder included with your laser).
3. Screw the small panel to the actuator carriage.
4. Remove the front panel of the Acro X axis cart.
5. Install the structure in its place.
6. Connect the stepper motor to your controller.
7. Adjust the appropriate values (steps/mm) for Z in the GRBL settings.

You're done! You now have an automatic, motorized Z-axis.
