I've been trying to connect a 2+ meter wire to a nema 17 motor. Usually the motors I buy come with a 1m cable, which is too short for this application. The Nema17 needs a 4 wire connection. So I figured I'd just use a normal 4 conductor 20awg insulated wire and attach a 6-prong jst ph connector on the end which mates with the connector on the stepper I bought.
I am noticing that many stepper motor's external wires are 4 conductors but they are all side by side (like picture below) instead of twisted and insulated together like I am accustomed. Is there a reason for this, or are the manufacturers doing this just because it's cheaper.
