What is meant by 4-core CY cable?

Yeah its the 2.2Kw might aswell bulk it up incase anything changes.

The trouble with 2.5mm is the connecting in to the plug on the spindle and 1.5mm will carry in the region of 18A which is more than enough. Good luck with the build. ..Clive

Crap i forgot abut that, thanks for the heads up

I'm with Clive 1.5mm is fine for spindle and much easier as you can use same cable used on motors even thou only 3 wires are used. Can use 4th wire for an earth if you like but personally I don't bother as never needed to.!

Yes they are great but they are expensive so it gets a close call between them and Servo's so do some shopping around if your thinking to use them.
Only thing they have in favor over Servo's IMO is that they are easy to use and setup with no messing around tuning drives etc.

Servo's will be better if you want higher feeds and torque.

That said if you use Normal steppers tuned correctly and running on good drives then you won't have any issues. Will say thou D-Man if your using 34 motors you want High powered AC voltage drives to get the best from them.! They cost more but also make build control box easier as you don't need a PSU for the drives so don't cost that much more in end.
