I think it'd be easy to automate a PID tuning system like Ziegler-Nichols <http://en.wikipedia.org/wiki/PID_tuning#Ziegler.E2.80.93Nichols_method>. It'll get you in the ballpark at least. > This same thing could be applied to stepper systems too. No, stepper tuning just requires looking up the step/dir waveform timing specs from the manufacturer.
