Tool Boards Suddenly Not Communicating
-
I've been running my 4 tool tool changer with tool boards for a couple months now, but all of the sudden my T2 and T3 have stopped communicating. Here's a video showing their behavior:

As you can see, the first 2 tools, T0 and T1, have slow blinking red lights in sync with the main board. However, T2 and T3 have rapidly blinking red lights, and their hotend fans are both turned on, both of these states indicate the absence of communication between the tool boards and the Duet 3.
I am running a tool distro board, and have checked all 8 CAN wires for continuity from end to end and they're all fine.
