Stepper moters spin in wrong direction?

[William]

Hi, f your stepper motor is in the opposite direction to what you need,
May be caused by an incorrect motor position setting on the firmware.
For specific operations, you can refer to this: http://www.geeetech.com/forum/viewtopic ... 17&t=17037
I hope this can help you.

Just put the wrong small engine will create very annoying sound. I think they were broken.
