I had my ShopBot computer melt down and had to replace it - my ShopBot seems to get around alright: it zero's out ok on x,y, = 0,0 as well as the z zero plate defining z=0. However, when I try to run a routine or do any jog or move commands where the bit needs to get within say 0.3" of the y axis I get an "Y-Value Beyond Limits" error message. I can do a Resume Move, which will allow me to continue until I need to once again get back close to the Y=0.
Any clues ?
