I knew you were using Rhino for your CAD, but hadn't looked at it enough to know it has CNC control build in. Boy, that's an expensive program! I think it might be even more expensive than AutoCAD..... maybe not, it was around $4K/seat, but that was several years ago now I think of it. That's why I like DraftSight..... price wise for hobby use anyway. Shucks, I had the above all typed up to post, but for some reason it didn't get posted.
