* Can you spin the rotor by hand when it's disconnected?

All three steppers spin freely.

* Have you checked winding continuity?

They all measure close to 4 ohms

* Are the windings connected properly?

I have a connector to the stepper with colored wires to each winding (a+ -
green, a- - blue, b+ - black, b- - red).  Yes, they are verified connected
to the correct pin (1st, 3rd, 4th and 6th) respectively.

As for trying the steppers with a 12V supply, I haven't gotten help for
that yet.
