Hi Terry, I can assure you 100% that the Cslabs or any other open-loop Step/Dir controller for that matter knows nothing about the drive which is attached, they just send out pulses and trust the drive receives them. Now, you can get drives that handle pulses timings differently but I've yet to see a Closed-loop drive or any drive for that matter that doesn't work with the Cslabs controller. However, pulse timing issues can usually be dealt with in the control software motor tuning.
