You hit the nail right on the head. I had my saved position set to the center of the machine 200 by 200 mm. When I added the Laser Hight Adjustor, that set the center to 200 x 206 mm. I set this using the “Set Origin” button. Today when I was opened it I used the move to position which was 200 by 200 mm, and for some reason it would do everything, but, START. After reading your post I reset the Set position for CENTER to 200 by 206 mm and it works. Who would have thunk it? Thanks
