Hello,

My problem is that when trying home the Z axis the unit does not see the proximity switch (I believe) and the unit runs completely to the top and jams up. I replace the proximity switch, the switch is normally close- light is on and does change state when I place a screw driver on it. X & Y axis work find. When I look down the back side of the unit, I do not see a trip flag and not sure were it would be located?

Thanks

If replace a new proximity switch still the same problem, you might need to check the feedback from the proximity switch to the CNC controller.

I found the Z proximity switch on the diagnostics screen and place a magnet on it and it changes from 0 to 1, so looks like its communicating back. The one thing that's really puzzling, is I cant seem to figure out were the trigger flag for this proximity switch is. almost like something is missing there. Not sure what trigger the change of state.

I appreciate your responses.

Thanks
