Speed controllers won't communicate w/robot controller

You say that plugging the other end into last year's RC made things work, so I doubt it's a connection problem at the Victor. But in case it is, we have discovered that this year's Victors are very finicky about exactly what angle the PWM cable pins are inserted at. Half the Victors weren't responding. I bent the pin on the white end just a teeny bit off center and suddenly all was well.

I will try that tomorrow, although the pins are already pretty well bent up and it seems rather odd that all 6 would show the same problem if that was in fact it. But it's something to try...

Well we did not work around it. We hooked up the motors to the victors and the motors ran so I don't think our whole victor is broke just the led. because sometimes when we drive the led just shuts off, but everything still works. That was not much help but try hooking up a motor to the victor, and if that does not work then I would start worrying about the RC like the others said.

You can be getting cross chatter from the data cables. If your input power wires(postitive and ground) are too close to the data cables, it will cause the robot not to work. The power input wires create a magnetic field which messes with the cycle of the victor. Try moving your data cables away from the power input wires.

They aren't very close.
