Hello when my machine is set to ref all home the z-axis goes to trip the switch but it will not back off. The reset button lights and I have to turn the power off move it off the switch by hand then power it back up and hit the reset button. Then the machine will move again



    Thanks Bruce

same for me think its the wiring of the switches  I been told

  I figured it out    thanks       that's what is was my switches were wrong.

if you have a wiring diagram would be helpful

This can be caused by switch bounce - try adding some debounce in settings, maybe 2000 and work downwards.

  Thanks for the answers I had the switches wired wrong. I fixed it.

 Thanks all
 Bruce
