I have decided to use XLR connectors between the control box and the steppers. I have ordered some 5pin with male for the cable and female for the cabinet. The four cores of my cy will go into pins 2-5 with the shielding braid going into pin 1 like this how to video:

My question is do you connect the shield as you come into the cabinet or right at the point of connection with the drives? And do you go straight to the cabinet/back plate or run a wire to the star ground. Apologies if this seems basic to some of you!

Not saying that this is right, or the only way to do it, but it is working for me...

I use 4-way XLR. CY cable from the motor has its braid soldered to the shield terminal in the XLR plug. Because I don't trust the socket to make a sound electrical connection to the powder-coated cabinet, I run an earth wire inside the cabinet from the earth terminal on each socket to the star earth. Each XLR socket has CY cable to the stepper driver with the shield connected to the socket's earth tag (along with the wire to the star point). I should probably not have daisy-chained the socket earths to each other and then to the star point as each should have had its own wire (probably). I have had no noise issues with my cabinet wiring. At least, not as far as I know.
