I have the Gamma and Epsilon Motor connections connected to 2 motors that will move one of the axes on my machine. I have the control pins jumpered and I am able to drive both motors as expected. These 2 motors need to be in sync, but one of them needs to do the opposite of the other. I experimented and determined that if I simply reverse the wiring to one of the motors, then I get the result that I’m expecting.
From the wiring information about pairs and coils and such, which I only understand at a very basic level, I think I’m just making AABB into BBAA on the other motor which changes the direction.
Is this making any sense? I don’t want to fry things, but I feel like this is the way to accomplish what I’m after.

Exchanging the wires of pole A with the pole B wires will not reverse the motor direction. You must invert one, and just one, pole.
For instance, change from:
A+A-B+B-
to:
A+A-B-B+
you can easily find the coils pair by simply short circuit 2 wire at a time and turn the shaft manually, the motor shaft is harder to turn if one coil(A+A- or B+B-) is short-circuited.
If you connect the motor wrongly it just doesn’t work, you don’t fry anything, just strange noises…
And yes, by just reversing the connection you invert the rotation of the motor.
The stepper driver doesn’t know how the motors are connected, as far as you keep the total current drain at 2 Amp maximum if is a standard driver.
The last thing, try to connect one motor at a time and find the right rotation before you connect both together.
Excellent, thanks for the follow up.
