Good point Neal, thank you sharing your experience, but we must remember that the cnc was working before very well and I have not touch the Mach3 configuration since. It’s true also that I have single switch for Home and Limit. In addition, when Homing if the axis moves even a millimeter I will see/hear it and this doesn’t happen, What happens as soon the Gantry touches the Home switch I hear it clicking the switch and then the Gantry stops moving then the DRO numbers start to move to zeros and when it does I get the message “Limit switch is triggered”.

First I will try to fix it without touching the Mach3 configuration which was good and I did 3 sample cuts with no problem at all
