maybe someone can answer this question.
when I cut a round profile on my cnc router
and am going slow 150 ipm the servo motor is turning
at 46 rpm ( direct pinion drive to rack )
I get jagget cuts on diagonal and radius.
looks like a zix zag cut.
So I run same program use mach to increase
cutting speed to over 300 ipm servo motor turns at
about 90 rpm the jitter is almost goes away.
I thought it was the signal to the motors being slow.
If I speed it up and the movement gets smoother
So It cant be the slow signal.
Am I right?
What is going on?
Thanks,
Bob
