steppers wacky

I am finally getting around to putting my machine together. I got mach installed and the kelling 4030s wired up.

when I turn on the power to the controller the motors vibrate and hop around. The spindles turn.

They are the 8 wire motors from kelling that came a a kit. Any help would be great.

Thanks
Bill

Sounds like you got the motor wires put on in the wrong order.

Wired wrong or an incredibly huge amount of induction occuring

Is your controller connected to your computer? Is Mach3 loaded and open?

New parallel cable fixed it.
