I think you've all hit the nail on the head, at least with my HPGL based controller. If I move this machine into a money making endevour, I'll probably need to replace the controller and drivers with mach 3 / gecko or similar to increase its speed but for now even with the 1 degree increments it seems pretty smooth. Perhaps I'll cut a 4' table to see what code it generates and to see if I can detect the flat sections around the circumphrence. From the doc it should be glaring, but from the small amount I've cut I have no indication it will show up as quite such rough chords.
I'll keep you posted when I cut such a piece.
Thanks again!
