Ok... I have heard that the Smooth Stepper takes a lot of load off the CPU. How exactly does it do that?
How does it deal with the typical erratic on demand not hardware driven behavior of a USB port? Does it actually buffer instructions internally?
Would using a Smooth Stepper allow for use of the tool path screen with larger files on Mach 3? If so, how much larger?
I already own one I am laying out on a mill, and these questions keep me up late at night.

If you download the manual then it gives a basic explanation.

Yes, it uses a hardware method to generate step pulses, up to 4MHZ. Much faster than you could do with a "windows" PC. Mach 3 motion planner sends movement instructions to the smooth stepper, which in turn converts it to step/direction pulses. SS can buffer some of it in case Mach 3 has a slight delay.
