Limit Switches

Six limit switches are installed and wired. The multiple core CY cable is used, although only two wires are required.

All six switches are wired in series to a single controller input, and they are configured to operate as both limit and home switches.

These switches will stop the motion if any part attempts to move beyond the end stops, and are also used by the controller to locate the X, Y and Z axis to a starting or home position.
