So i recently purchased a large 3d printer, it is a Tronxy 5xs 40 and it has two z motors and one x and one y. With the controls, and while messing with it, all motors seem to move in the correct directions, However, when i click auto home, and this is on a Marlin, it goes the opposite direction on the Y axis. HOWEVER, flipping the wires, belts and anything else does nothing. To me this makes no sense, should it not move towards 0 instead of max? it grinds each time and i have to emergency shut off the motors. I doubt it is a wiring issue, as i have checked it twice and colors, and plugs are all correct and labeled. Since it moves with commands correctly, i doubt it is a program error. How do to change this or fix this issue?
