So have I, Dave, and I wound up bypassing that particular opto in the board I used to drive my G0704, but this one doesn't have the opto's that I know of. Because they are slow, I've found them far more trouble than they are worth as a safety measure. I'd much druther trust a good grounding system, star topology of course.
