So this never happened before. I had turned on and warmed up my machine. When I went to move it to the material to Z zero it, I noticed all my numbers where off. I normally have it go to 12, 10 when it's done cutting so it's easy to change the bit and usually clear of most material. When I started moving it from there with the keypad I noticed it was reading something strange, like -17, -14 or something like that. I don't remember the exact numbers but they sure were wrong, as well as the Z number. So I stopped and re zeroed it all. I had shut down everything in my usual order the day before. We didn't have a powere failure to my knowledge becasue one computer I leave on all the time was still on. Anyone else have this happen? It's the first really weird thing it has done since I've had it.
