Re: no voltage across PWM pins on roboRIO

Thanks Ether, I'll be sure to double check the measurement tomorrow.
Lukas, I believe the power LED was on (I think it was red) and we did find some metal shavings inside it. A simple short doesn't (usually) result in permanent damage right?

When we were testing an alternate encoder, we ran a separate motor from a separate power supply while plugging the encoder wires into the roboRIO on the robot (running on a different power supply). Someone mentioned a potential issue with the two being grounded differently (my understanding is if everything is run off the same power supply, the grounded wire from the encoder connected to the roboRIO eventually connects back with the grounded wire from the motor and goes to the battery ground). Is this two power supply setup an issue?
