Suitable cable chain

[AndyUK]

No problem - if it helps my four core CY cable (1.5mm2) is about the max you can use with the 2.2kW water cooled spindles before the GX20 plug becomes silly to solder on, and it's overkill in terms of the current capacity. I used it for both motors and spindle. That measured ~9mm Diameter. I used three 8mm external 5mm internal Polyurethane pipes (two water cooling and one air supply), and my limit switches use 3 core 0.5mm CY which is 7mm in diameter. The probe is the only other thing that goes through my chains, but I've taken the 0V from one of the limit switches.
