Kirk, Problem is that I bought the cnc4pc board with the speed controller in mind. The doc said it supported emc, so I guess there must be a way. Arturo of cnc4pc is looking into it.
So if I can avoid adding extra hardware, this would be nice. I agree if you want very fine control, your solution would be the best way to go.
