# Example program

In the above program the Z axis will move to Z -10 and wait for the probe to touch. Once the probe touches, the Z axis will stop and the program will move to the next gcode line. If the probe is not touched before it reaches Z -10 location then the program stops and an alarm is displayed on the screen.
