Oh. I'm setting up for using cat7 solid core shielded ethernet for limits.
Think I'll have to do a little trial to check it doesn't burn up first before attaching to machine then.

I've used 0.5mm for control box (RS components, grey) and 1mm for steppers.
I think my servo is 1.5mm.

And yes. The UK is total crap or overpriced for supplies.
