YAxis Motors working in reverse of one another

I am one step away from carving but cannot get thru the electronics calibration. When I test the Y Axis the motors seem to be working in reverse and the gantry moves out of square. I have tried revervsing the GRBL but has not worked. The X axis moves fine and the Z axis moves fine.

If you look closely at the wiring instructions, it tells you that you need to reverse two of the wires when connecting the 2 Y axis motors together.

I will check it out. Thank you

@JonUdell the reason for this is you actually want them spinning in the opposite direction to get forward motion on the gantry.

Thanks for this post and reply. Finished mine last night and missed this step also.
