Henrik, Thank you and thanks for your explanation. I've not done any work with the stepper motors so I'm still learning. I'm actually not trying to get much speed out of the stepper. I will be driving a conveyer and it will be moving small parts under my spray nozzle so it's not going to go fast at all so the parts can get evenly coated.

I'm going to start to look into generating the pulse with HPWM I've never done that before

Thanks for letting me know about that ds device good to know.

David
