Lathe controller

specifically, 3.25 million pulses/minute is 54 KHz!

So lets do the maths:
200 ppr x 25 microsteps x 650 rpm = 3,250,000 pulses per minute (or 3.25 mHz).

Just a minor error,
3.250.000 pulses per minute divede by 60 equals........not 3.25 MHz.
Hz is rate per second, not minute.

Ooops it has been a long day. I knew it did not look right but my brain was seized!

And I also remember now I did use 40x stepping before backing it down so I had some margin for safety so about 86.6 kHz
