Re: [CAD_CAM_EDM_DRO] BobCAD users

Alex,

I ran in to a similar problem last night. This time it wasn't a pocket
function, just an "auto cut" that went out of control and repeated some 20
times (the previous 3 cuts worked fine).

No explanation or fix that I know of other than manually deleting extra
code - a real pain.

I think I need some $$$ to upgrade to Vector.

James
