I'm playing with Chuck's code...
...to drive a 200 step/rev stepper, being driven with an 8-step microstepping driver, feeding a 12:1 reduction drive.
I'm seeing some odd behaviour where the motor only stops on the first movement, after that it just keeps going. This behaviour depends on the initial timing settings.
I *think* there's an overflow issue somewhere but I'd like to go back to the original work by David Austin. I've found the original article but not his original code.
Does anyone have a copy of the original source code?
I've ported to Codevision but that shouldn't be a problem.
