Most (including me use 4 wire CY shielded cable) on their machines - I think I got mine from RS Components, but that's likely the expensive route.....you'll need to make sure all your shielding is grounded to a single point to mains ground (a star point is the term iirc) and make sure the far end of the cables at the motors etc. is not contacting anything to avoid ground loops (these are bad). I used bits of heat shrink to ensure isolation for the far ends.

Hope that helps......
