dm542t motor reversal?

LIkely the answer is no, hope I am wrong.

I am using linuxcnc 2.7.15 breakout board with printer cable
My X axis has twin rack/pinion drive, motors need to turn in opposite directions. Modifying HAL is beyond me.

I tried reversing the motor phase connections on one driver/motor and the motors still both spun the same direction. Should clarify, both CW and CCW but in sync not opposite as I need.
I have both x axis motors connected to P2 P3 not ideal I realize.

I wonder if it is possible to rearrange the control connectors to reverse one motor? I have not messed with this. The jumpers bringing power to pul+ Dir+ and Ena+  puzzle me. Ena- goes to P2 and Dir- goes to P3.

Thank you.

One winding ONLY, not both, and not phases.
Single phase, one winding, two wires, that is the only thing you need to change for it to change direction.
Edit:
NEVER while the drive is powered!!!

So appreciated! I will go take a crack at that right now.
I disconnect ALL the power! always.

Instant fix. Tommy, thank you. I have been slamming my head against that for days.

You are welcomed, always.
