We recently just assembled a new drivetrain and when we powered it on, our talon srx’s and victor spx’s were alternating off/red signifying a CAN BUS not detected error. Our PDP lights were both flashing red. We made sure our RIO firmware and image were up to date. Our CAN BUS wiring, per the talon srx user manual goes from the rio, to a talon, to another talon, and so on until it reaches the PDP for the end. We tried switching the rio but that did not help. When we pull up the Phoenix Tuner and connect it to the robot, it successfully connects but no motor controllers show up on the CAN devices tab, which makes sense. We tugged and pulled the CAN wires and they are all sturdy and firm. They are soldered together. I won’t have acess to the robot until next week so I won’t be able to test anything.
Thanks in advance for all the help.
