The attempt to help is surely appreciable but seems to be lacking any structure. From my perspective, it is not clear: 1. Exactly which hardware we are talking about 2. The goal of how this should be connected 3. Which additional hardware (e.g., Eddy) is involved 4. Finally, a `klippy.log` @ten57: May I propose: 1. List exactly all your hardware components—full and exact name including revision 2. Draw a rough sketch of how you connected them or intend to do so. You may look at [this link](https://klipper.discourse.group/t/can-basics/22591#p-73309-h-2-klipper-architectures-with-can-8) for an idea 3. Provide a `klippy.log` 4. Reduce to the minimum, e.g., only the Kraken board. 5. Concentrate on this board. What is flashed and how? How is it connected? ---

Flash board (Katapult + Klipper) according to [BigTreeTech Kraken | Esoterical’s CANBus Guide](https://canbus.esoterical.online/mainboard_flashing/common_hardware/BigTreeTech%20Kraken/README.html) and then follow the [USB-CAN-Bridge Mainboard](https://canbus.esoterical.online/Final_Steps.html#usb-can-bridge-mainboard) This setup does not return anything by `ls /dev/serial/by-id/*` unless the board is in Katapult mode. The `printer.cfg` needs to contain the CAN UUID as described in the guide. ---
