I'm writing a program which controls 3 steppers motors. I tried to use time.delay to control the speed of my steppers. My problem is that one of my motors need a delay less than 15us and from what I've calculated with a timer, it seems the delay function itself has a delay around 70us. Is there any way I can achieve the speed I want for stepper? I tried to use PWM functions but they also seem to have a limit for frequency.
