Re: servo jitter when running Jaguar on RS-775

We are experiencing the same exact issue you described.

We use 2 servos, one to release the deployment system, and one to release the actual minibot. In both cases the servos would jitter as we ran our two 775s for our elevator system.

After discovering our 2nd set of motors both had internal shorts (the 1st set did as well), we managed to scrounge up 2 more 775s that were sans-short. Since replacing those motors the problem has gone away.

It was an extremely frustrating problem because we had no idea when/if the deployment system would trigger as we ran our elevator.

I've noted the other suggestions in this thread, but I know for a fact the wires running to the motors are not close to the PWM servo cables. The capacitor may be a helpful solution, we'll have to look into it as a fall back.
