I think it's got to do with the wiring of my motors to the ramps board. On the ramps board there are 4 slots for wires, which are called 1a, 1b, 2a, and 2b. Now my stepper motors wires are called A+ (green wire), A- (black wire), B+ (red wire) and B- (blue wire). which color wire goes into which slot on the ramps board? I tried a few combinations, but the motor did not go smoothly, it made a loud noise, and hardly moved. I'm scared to try out new combinations in case i burn it. Why is it not moving the way it should and how do I wire it?</p><p style="box-sizing: content-box; margin: 0px; font-size: 1rem; color: rgb(46, 56, 54); font-family: proxima-nova, "Helvetica Neue", Helvetica-Neue, Helvetica, Arial, "Nimbus Sans L", sans-serif; line-height: 29.568px; background-color: rgb(236, 254, 251);">Thank you so much for your time, cheers Mitch. </p>

Repetier

That is more a hardware thing, so not really my area. Most motors for 3d printer come with a 4 pin header so you only put it on the pins. Mine have the same colors and order is blue,red,green,black in case it helps. Rotating it 180° just changes move direction.
