I'm building a wood router, and am using steppers with Gecko's. I happened on an incredible deal for a 600 oz brushed DC servo. I would like to use the servo for my x axis, and steppers on the others. I plan on driving it with a gecko 320 also. Does Mach not care, or would I have to specify somewhere? As long as all the axis are on step signals, and I have the steps per inch set right, I wouldn't think it'd matter. But please, someone correct me if I'm wrong.
