@ Bobc, you're right on the money. Keystone 3568.
And I'm re-visiting the diodes. Eliminating them actually and moving to something else, maybe a MOSFET for reverse polarity protection.
@Cefiar,
thanks for the pointers!
Maybe I'm a curmudgeon, but I like the USB-B connector. I'm kinda leery of those mini and micro connectors. And since I've got the space for it I might as well use it.
And good call on the stepper lines. I'll bump them up to 90 mils.
I tried adding the polarized connectors, but they leave no room as the stepper driver headers are right up against the jumpers. It would be a bear to get them in and out. Ideally I would like to have gone with DIP switches instead of jumpers, but they take up so much room.
