I am finally getting around to setting my machine up. It is a 6040 from CNCEST, it is USB, and I am using Mach3. First, I installed and set up my limit switches, all in series and normally closed, and they worked good. When I hit the Ref All Home button, it would home the Z axis, then the Y, and then the X. After homing, the switches then worked as limit switches. After spending a week or so getting everything else set up, just when I thought I was ready to start cutting, when I now hit the Ref All Home button, instead of taking the Z axis home, the Y axis drives all the way to the back, hitting the switch, and instead of acting as a home switch, it acts as a limit switch, and stops everything until I physically move it off of the switch and hit reset. I looked at the script for the Ref All Home button, and it was as it should be. What would cause this, and what can I do to fix it.
Your help is greatly appreciated.
