Hello,

When using EMC2 with stepper motors and software generated steps the highest 
step rate seems to be limited by the computer latency. We have a clear formula 
to calculate that rate based on the stepper driver requirements and the 
computer latency.

How do we calculate the highest step rate when we use hardware generated steps 
(Pico, Mesa, etc.)? How does the computer latency effect these rates? Are there 
other factors?

Thanks,

Rick
