How do you get the X zero, Y zero, and Z zero LEDs to change from green to red after you hit an E-Stop? (this would indicate that you should do a "home ref." before continuing) My system used to do this and now for some reason it is not!

I dont' recall an estop de-referencing the axis's.
Bumping a limit switch will though.

Or....putting this in the macro pump works as well.

If GetOEMLED (800) Then
DoOEMButton 240
End If
