Hey, Paul. That was pretty much what I was thinking..
I wonder, if you can take the outputs of 2 optocouplers and put them in series to make an AND-gate, then, your driver board would still be isolated from the controller board?? You would still need a voltage divider to drive the optocouplers, I think..

I'm glad you like my "cheesy” controller, I was just so glad to have it work even better than I had hoped.. I’ve blown out 4 IGBTs (300 and 400A) and a pile of mosfets, just thru ignorance..
