I just installed a Ramps 1.4 board on to my Anet A8. Everything worked as it should except for the Z axis motors. The Ramps board I have contains two headers for each Z axis motor.

When both motors are connected, one of the motors squeals like something awful. When I disconnect one motor it turns smooth as butter. I have tried this for both motors and when only one is connected it works as it should but does not with both.

Has anyone experienced this? Is there a simple remedy for this issue? Any help is appreciated.

Found the issue. The steps were set way to high. I lowered my steps to 500 and the steppers seem to perform as they should.
