Source for 4 conductor wire for steppers?

Thanks... I'll put CAT-5 on my do not use list for the new plasma table.

Home depot has 4-conductor braided shielded wire in 22 guage. I'm not sure what it's intended purposes is, but it is nice stuff. The color is gray.

Now to the important questions, how much current are your motors going to be running, and how long are the cables going to be, and what is your power supply voltage? 22awg is roughly .16 ohms per 10'. A 6A motor on a 20' cable (40' or wire on one phase) is going to drop roughly 4V across the wire. So if you were running a 34V power supply, 12% of the supply voltage will be wasted. If it's a 24V supply it will be worse. It's pretty easy to find 18ga single strand wire at home supplies and automotive supply houses. A drill can serve to make your own twisted pairs and/or nylon electrical ties can dress the wires together. Plastic loom or wire netting can dress it further if appearance is an issue.

Wire gage really doesn't matter so long as the cable doesn't get hot. The stuff about 6A thru a 22-gage wire is true but as motor speed increases, current decreases. There would be little to noticable decrease in motor peformance.
