Recently our setup two of the new Neo Vortexs for our intake via CAN. They’re both updated and setup at different IDs. Whenever we have one individually connected to our whole system, it works! When we have both connected together as the only things in the whole system, it works! When we connect both Vortex’s into the entire system, all our CAN items crash. All that is setup right now is swerve drive and a CANdle. Anyone have any solutions?
Can you please provide more information as to what is on your CAN bus and how it is wired?
We need some additional information to help determine the cause of the problem.

Do all swerve devices + CANdle communicate just fine before you rewired to add the new motors?
Where in the chain were the motors added?
By items crashing, are you getting some error in the driver station? Or are you losing communication to all CAN devices?
So all that is connected is around 8 CANSparkMax and 4 encoders all for swerve. 1 CANdle for LEDS, and the 2 Vortex’s for motors. The line goes all swerve, CANdle, then at the end is the Vortex’s.
By items crashing I mean both the CANdle and encoders indicator lights go from blinking green, to blinking red when both Vortex’s are plugged in.
Sorry if this is obvious, but do you terminate the can bus at the PDH (with the resistor switch turned on) or at a separate resistor? We’ve had behaviour like you describe when the bus isn’t properly terminated. Once you get above a certain number of devices (of any type, not just Vortexs) on an unterminated bus (7 or 8 sounds right) they all stop working.
