A lot of people on here use 4 core CY cable 1mm or 1.5mm. What type of lead screw are you looking for? ..Clive

You will want to buy FLEX CABLE, SHIELDED, 18AWG, 4CORE /0.8mm/

ALPHA WIRE,2424C SL005 is the cable i use. Yeah, its better than the Chinese one the others sell for almost the same money.

hi guys thanks for the cable info :) and clive im currently using threaded bar just for the build and to check motion etc but i do want to use something more accurate and robust but the price tags are way out of my league from what i have seen, was maybe considering chain drive?, my bed size is 1200x1000mm

I dont like CY cable for stepper motors. I like it for the spindle to VFD. The others are = "ebay search stepper cable" . What i say is that better buy brand cable for steppers.

Brand cable like http://www.control-cables.co.uk/cy-cable/ there are lots of "branded" cable please inform me and others why you don't like CY cable and why it is ok for spindle and not for stepper motors. ..Clive

OK,

For spindle i buy SY cable. Sorry for the mistake.



CY cable is not true "flex" cable . Nothing wrong with it.

Minimum bending radius for:flexing:
20 x cable outer diameterstatic:
6 x cable outer diameter

Temperature range:
flexing: -5°C up to +70 °Cstatic: -40 °C up to +70°C





I like "flex cable" . Flexy, you know. Easy to bend , thin for the size, easy to solder.
OPERATING TEMPERATURE:
■ –20°C to 60°C







But you Clive, feel free to buy and to recommend whatever cable you like. I just stated my recommendation. Its personal preference. Nothing more.

Well from the link I posted "CY cables come with a grey sheath, are highly flexible multi core cables with (class 5) copper conductors. They also have a voltage rating of 300/500v, having been manufactured to meet the requirements of BS6500 and VDE0250." it seems they are flexi.
Anyway we will have to agree to disagree. ..Clive
