What is interesting here is Cartierusm stated no spindle speed with Vn .40, just 7rpm, that is exactly what I got. When Vn.32 was tried looks like it was sucessful.
I`ve tried vn.20 and spindle speed is ok, vn.40 no spindle speed,no matter what the debounce or M3. I now need to try V.32, but I`m 6000miles from my workshop at the moment so that will have to wait! Anyone got spindle speed with Vn.40 and parallel port? Can you share your relevant "Turn" settings please!
Thanks, Woody.
