Problems with Rambo 1.4 Dual End Stop Firmware Release 2.0.5.4

Clone Mini rambo motors dont move Nema 17

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.

This mini rambo board shows the BAAB configuration on the underside of the board. Can you look at the underside of your black rambo and see if there are any labels that would indicate your motors aren’t wired in AABB?
