Re: OnStep to Servo or External Step/Dir drive

Note that for GENERIC and SERVO types the minimum pulse width is a recommendation and OnStep will only warn if your MCU is below that (where for other stepper drivers it won't let you compile.) 

For the T3.5 I measured 500ns pulse width, not sure why there's a discrepancy but I probably compiled for fastest code where you might not have?  I shaved a little off of my values to be on the safe side too so probably measured 600ns or so.
