Took a little to find and download what pin makes what relay work. Nice fit, finish, and operation when I did figure the pins to relays

Worked as hoped!
Did what it was supposed to. Concurrently connected and controlled 2 NEMA 34 & 1 NEMA 23 stepper motor(s), 1 5VDC relay & 1 AC relay from the shield attached to an Arduino UNO, and programmed via LabVIEW 13.
