[Emc-users] Power and data cables for CNC

I wonder what kind of power and data cables would you recommend for use in X-Y-Z CNC about 1.2mx1m size? Besides power, it's not clear to me how many data lines for sensors, encoders, motor control, etc. are needed in general. Is it preferable to carry power and handful of control signals to

Note that data cables will need to be screened. I'm using twisted pair, (OK CAT5, because it was lying around) this is working for my home switches, but when I joined up the Z Y limit switches (I don't have enough inputs for one each) I could no longer turn the machine on. HAL scope

Rafael The wires you need will depend on what motors you are using, the arrangement of limit/home switches and if encoders are being used. Once you know these things you can choose the cable. For example I have built a machine of similar size to yours. It's driven by three 3.1Nm steppers
