Re: Help with wire sizing

<< From: Joe Vicars <jvicars@...>

I want to use CAT 5 network cable for wiring small stepper motors

Any input on this? Is this OK

Joe,
My only problem would be wire flexing. I'm using some stranded 16 ga wire
on my 7 amp drivers. The stationary Z axis motor is not a concern but my x
and y motors move quite a bit. I'm bracing for trouble.
Cat 5 cable in my opinion would not last very long assuming the current
capacity is there. If you can support the wire a distance away from the RJ-45
connections or however you terminate, maybe it may last a while. I'd rather
take 18 or 16 ga MTW and twist it like cat 5 for noise reduction. Put a cable
tie every 6 inches or so. I've looked at buying flexible machine cable, they
wanted $500 for 100 feet or some such outrageous thing.
