We have always battled with how much rotation is to much. We have gone past 360 degrees in the past and had software stops on it. We would have to have a lot of extra slack in the system as it would shorten with the rotation. We also found it would get confusing at times where you were in the rotation. We had a button that would re-zero it if we got lost. Lets just say i wish the wires would stretch more at times.

We have tried to go with less rotation in the last few years, nothing more than 270 or so. If you are running balls through the center of the turret you will then have to run the wire around the outside which could limit you even more.

Of course you could try slip-rings. We have found them to be cost and time prohibitive but they may work for your application
