Re: [CAD_CAM_EDM_DRO] Re: USB ports ?

The original poster stated he was using TCNC, which only does step and
direction signaling, as far as I know. (I've got 3 machines running with
it.)

I agree that USB would probably work with smart controllers that aren't
sensitive to data timing. There is disagreement about using USB
converters to generate step and direction pulses.
