Hi,
we need more information before we can help. Probing is enacted by the motion controller, being realtime, under
Machs supervision.
What motion controller are you using?
Do you have it setup correctly, that is can you issue MDI commands like G0's and G1's?
Do you have the steps per unit value correctly programmed in each of the axes? That is if you command G0 X4,
does it travel exactly 4 inches. I am assuming you are using inch units?
How are you probing, that is which button or Mach function are you using?
Have you tried to MDI a G31?
