Well - I gave up trying to figure it out and scaled the velocity from the
encoder counter by 16.66 and now it read correctly. So - boring at 300RPM
and .001 IPR gives me .3IPM which seems right.
Awesome - now when I slow the spindle rpm - the IPM slows also. (taking the
same cut at .001
I don't know if you're still trying to figure this out.
What was the encoder scale set to and how many pulses per rev does the
encoder put out. If you're using a quadrature encoder with 250
pulses/rev, the scale should be 16.67 = (250 pulses/rev) * (4
quadrature counts per pulse) / (60
So - I have some cylinders that need to be bored and was thinking to my
self - it would be cool to try out G95 so that if I want to slow/speed
up the spindle speed I will still be taking the same amount of material
out (say .001 per rev)
I just thought I would hook motion.spindle-speed-in

Not answering the question, but I think G95 uses spindle position, not
velocity.
