Perhaps I'm confused?
It kind of looks like the drivers are (electrically) connected to the control by components. Are there any other connections that aren't obvious (perhaps in the other 2 hidden layers?)
If not, perhaps those drivers could be cut out and some clever plug connect them to the driver board? Or maybe that's a silly idea for some other reason?

it also has a desaturation isolated fault signal that goes right to the micro and a hardware fault circuit. Being a 4 layer board with no traces on the internal +5v and ground planes, all signal paths have a very small loop area. Also all signals are separated sufficiently so as not to cause cross talk. There are no cables that could pick up noise. Also, all signals that are square waves don't change sides of the board since they radiate at sharp points. I'll post the hole coordinates tomorrow.
