These symptoms sound like simple wiring issues. Students will make mistakes whether you use PWM or CAN bus, (and hopefully will learn from them).

However with PWM you must [1] Wire the devices, [2] Power the devices, [3] Code the devices, and then begin your troubleshooting. With CTRE CAN devices, you can do [1] and [2] only and then begin diagnosing (web-based config, LEDs, Driver Station, etc.).

Additionally the feedback we've received is that CAN bus is far simpler to wire than PWM.

To better answer the questions posed in this thread, I just added some content to the Talon user's guide (pages 35-37).
