Thank you very much, That appears to resolve the issue.  Now back to hooking up switches.

General Mach Discussion / Homing and limit issue.

« on: October 12, 2012, 08:31:10 PM »

Hello,

I am new to Mach 3. I have been evaluating it as I build a CNC machine. I am now to the stage where I am installing the limit switches. The machines x,y, and z axises function.

I placed the limit switches (currently only X and Y) in series on port 11. When I hit the ref X button (or Ref Y) button the axis move to zero but does not back off and the error message says that the limit switch has been activated. The only way I can get the machine to move is to reconfigure the inputs to not have limits.  When I only had an x limit it was working as expected, but when I added the y it started behaving this way.  Even the Auto limits and manual limits override does not allow me to jog until I reconfigure the inputs to not include limits.

Can someone examine my config and give me a clue to what I have done wrong.  I have read lots of topics on the forum and checked to make sure it is set up as I think it should be.
