    1mm^2 is fine, but I used 1.5mm^2 CY since that's what I have for the stepper motors and it's more efficient to buy the same for all. It's important to use shielded here and earth it well.

    Edit: Forgot to mention the reason you don't need so thick cable even though the current to the spindle is higher is it's mains voltage.
