Re: wire question

Thanks,

That makes total sense and it also makes it easier to ifentify what
is where.

Putting my stepper wires in one cable and power in another and low
voltage in a third is a little more costly in wires, but is eassier
to implement as lower count conductors are more available and I can
use lower gauge wire. a 25 conductor bundle seems a little large to
bend in the machine.

Assuming all 3 are shielded, then there is no problem with putting
them all in the same cable chain.

sound better ?
