I found several hints in this forum regarding the settings of "step pulse" and "pulse direction" parameters but their definition is still obscure to me.
The step pulse seems to be related to the duty cycle, I havo not idea about the pulse direction. Does someone have a clear definition?
The step pulse should be between 0 and 5 us, but I have to set it to 10 or the motors do not move. Moreover I often loose some step (not always), so I don't know how to set them.
