Re: New Victor SP Motor Controllers - Anyone else having issues?

We had the same issue with our second robot, even direct wiring the motors to the battery. One side ran smoothly, the other was slow and surging. We took off all the chain and wheels, and it was still doing it. We took the gearbox off the AM14U2 chassis and noticed that one of the CIM pinions was pushed against the cluster gear much closer than the other (and closer than other gear mesh throughout the gearbox). We rotated that CIM 180 degrees around its axis, and put in a bit more grease for good measure, and the problem cleared up.
