What are you using to generate the step pulses?
Andy, pardon my ignorance, what /would/ be generating the pulses?
Either software (through the parallel port or other GPIO) or a
hardware-based step generator such as a Pico, Mesa, Pluto,
I am just not completely comfortable without knowing those
values are optimum.
The values need to be long enough to trigger the drives, and that is
all. It's a digital thing, there is no optimum just long enough
You only need to worry about reducing the values if you are trying for

If you can find a way to get motor current data from the spindle drive
into HAL then LinuxCNC
Robert, thank you for your response and the time you've put into this.
I've been thinking about this and wonder what the ultimate solution for
my situation could be. It likely will involve variable feed rates,

This sounds like an impressive setup. I'm not familiar with the KL-8082H
particularly, so it's hard to say if having the drivers handle the feedback
would be better than piping it through linuxcnc. My assumption is that if
the drivers already handle it, you'd get the benefit of their controller /
