Hi Aaron,
The microstepping on KSTEP is fixed at 16uSteps/full step (3200 uSteps/revc for standard steppers). KFLOP can generate high step rates and KSTEP can accept high rates so there is no practical reason for reducing the resolution.
The 500KHz is for each axis. But that is just the speed the electronics will handle. Most motors will lose all torque and stall long before this rate (500KHz/3200x60=9375RPM

Thank you. I realize that I calculated for cycles per minute and not per second. The result of which were extremely high microstepping frequency of 9.6Mhz vs 160Khz at my theoretical max 3000 rpm.
