Thor, or should that be Zeus?

Do I need either of these cables to be shielded? 3 Core cable is common, shielding adds a fair bit to the price. I dont mind paying if its absolutely needed however no point if its just a 'nice to have'.

Any suggestions for cable for the 4KW type Chinese spindles?

Thanks

Personalty I would use 4 core cy cable 1.5mm for the spindle

You can buy it by the Mtr.

Thanks both.

And on the limit switches, screened or not?

Suppose I can just buy 50 meters of this stuff and use for both the limits and spindle, done.

Its not a twisted pair but at least its screened.

As with Clive I always use shielded.

Pity you didn't mention it when you were over here at the weekend - I bought full rolls of SY cable for the limits and steppers on my CNC Plasma table and have a fair bit left

No problem, thanks. You were already giving me free stuff, felt bad enough taking that, nevermind loads of other stuff too.

Chas As Andrew has stated. Here is a link to see the difference http://www.control-cables.co.uk/. But if you are ordering you can get 3 core 0.5mm will be fine as there is hardly any current to worry about in limit and signal circuits. Everybody will have their own opinion of course but these have been tried and tested by many.

How well does SY cable bend in energychain? I'm only used to using the 32amp 3 phase 5 core variant but I know that would be a bitch to fit unless you you used the same energy chain I see on skelly trailers (8" wide)

I regularly throw energy chain away this size if it would be use to you Chaz, far too big for me lol

SY cable and CY cable are different (I might be wrong here) SY is armoured cabling and I would think not suitable for moving cables in a cnc machine although perfect for the main feed. We used to use SY cabling for our 4 poster ramps (7.5T each) hardy shit but I still managed to break it lol.

In case your wondering drive over SY cable with all 3 axles of a trailer locked on will do it ;)
