Re: [CAD_CAM_EDM_DRO] Re: CNC Pulse jitter?

John,

It is not just the motors, but also the pulse instability. If you used the
exact same setup (power supply, driver, motor, machine) and could send it a
perfect pulse train you would find that the maximum reliable rate increases.
Yes, you will get a faster rate by going to lower inductance motors with a
higher voltage. But, that is just making the system more capable of handling
the jitters. In our hobby class machines it is a very low cost way to solve
the problem, but it does not mean that there is not a problem.
