Hood - Sorry, I was out all day yesterday.
The CSS worked very well, and it seemed to me, very smoothly. The wheels are 6 inches in diameter and I was cutting into the back by about 0.25 to lighten them - they are 1 inch thick. I wanted to start at the centre about 0.5 from the axle hole, and come out to a point about 1 inch from the rim.
I wrote the script that angled into the work, then ran parrallel to the finish. Botched the first one a bit (actually I needed a new tip on the tool) but after that it was a matter of mounting the hweel and pressing cycle start. I did all eight wheels in no time.
I can't really comment, I suppose, becasue the speed is constantly changing as the cut moves, but it seemed alright, and gave a nice finish.
As you know, I don't have a Bob, my index (single pulse) is optical reflector, straight to the computer.
