Have you considered external offsets for this? I have had moderate success
turning low lift cams with this feature.
I'm preparing the retrofit of a cylindrical grinder with LinuxCNC to
achieve camshaft and crankshaft grinding. With external offsets you don't
need a really precise servo spindle. A
I'm getting to the point where I need my own camshaft grinder.
The question I have is the G-code. The grinder has 2 basic components, a
rotary operation to turn the cam and a linear movement to move the grinding
head. For simplistic sake, say the G-code is 360 deg with the corresponding X
travel.
