The machine was just working fine on a profile cut. I switched to a v bit, zeroed Z and tried to run a v carve file. The router did not turn on, it moved about 6" to the right of where it was supposed to go, then began moving in X and Y only (no Z movement), When I stopped it, I got an Axis Designation Error. I shut everything down and restarted and when I tried to run the file again, I got a Stop Button is On message.
