If you look at the labels of the pins under the board, the X is labelled AABB, the Y, and Z are labelled BAAB. I have no idea why they do that, or how their feedback isn’t filled with bad reviews…
I would try using some extensions to swap the motor wires around so that the motors (which are wired AABB) are rerouted to be BAAB. So swap pins 1 and 3.
We’ve seen this before in the clone mini rambos, but I never knew it was labelled that way too.
