Hard Limit Error, A limit switch was triggered, this always results in the end of your job The only time a limit switch should be hit is during a homing cycle, at any other time it will stop the system Either your machine went to far in one direction and hit a switch or you have electrical noise getting into your limit switch ,

When each axis triggered it’s respective limit switch that was the 0 position for that axis The −1 comes from the ‘homing pull-off’ value we talked about in step #4 The reason that it’s negative is because of how the coordinate system is setup (X- is to the left, Y- is towards the front, Z- is down)

A CNC can have one or two limit switches per axis Limit switches have an advantage in open loop system Open loop means that there is no feedback to the controller Therefore, if steps are missed and the controller commands the axis to move past its travel range, the limit switch will trigger ,
