Hi Paulus,
Thank you for the info. I will have a look. To be honest I have no idea. I think I will do all 3 cables while I'm at it. Thanks again mate. really appreciate it. Terry.

As Rob has said I would suggest 4 core 0.75mm CY cable and connect the screen at the control box end to a star point (ie where all the ground points are connected)

Hi Clive, thank you. I'm going to try to get the cable today as I want to get the cnc back up and running. Thanks for your help and will let you know how I get on. I will have to have a look at how I'm going to ground the screen at the control box end. Thanks again, Terry.

Strip back the sheaf and solder a wire to the screen about 150mm long folded back along the cable and heat shrink over it, then fix that wire to a common earth point.

Thanks Clive, That's made things easier now I know what to do. Great advice mate, Thank you. Terry.
