Hi,

I hooked up my RAMPS 1.4 to my 3d printer, and got everything to work except the x and y axis motors. When I try and rotate them on repetier, they make a loud sound and stutter and then move a little bit very very roughly. but when I make my Z motor turn, again through repetier, it works perfectly, smoothly and without any sound.

I tested all the drivers, and all of them worked. next I tried exchanging the the y axis motor with the z motor. this time, the y motor worked perfectly, while the z motor made the same noise and hardly moved. This test means that there’s nothing wrong with my motors. Is this board faulty or are there solutions to fix this?

Thanks a lot, mitch.

Sounds like the wires are faulty

The wires on the RAMPS board? Do I need a new one?

Sorry I meant the wires from the ramps board to the motor
