Spindle possibly effecting stepper motors

[sbloom67]

Hi All, So now that I have my CNC working I am getting this wierd thing happening. As soon as I turn on my spindle , I have a quick click click of the steppers that are causing them to move a tiny bit. All of my wiring from the stepper drivers to the sterppers is shielded and the wires from the Sprindle controler to the spindle are double shielded. Anyone have any idea on how to stop this ??

Thanks Steven

Are the steppers already powered up and locked when you turn on the spindle? Or are you turning everything on at the same time? I always hear a small click when I turn on stepper controller and the stepper coils engage.

Yes, the steppers are all on, and the spindle controller is on as well. But when I start the spindle in mach3 thats when I see/hear the problem,

Thanks Steven
