I also attempted to follow https://github.com/Esoterical/voron_canbus, since I was out of resources but to no luck at all.
To be sure, I inserted a can0 file into /etc/network/interfaces.d, but I still cannot get the can0 network up at all after running ifconfig.
As a result, running this command ~/klippy-env/bin/python ~/klipper/scripts/canbus_query.py can0 returns this output:

Running the lsusb and ifconfig command shows that there is an OpenMoko device (which I am guessing is the UCAN).

Would someone be able to guide me on what I have done wrong, or is the UCAN / SB CAN TH faulty? Thank you!
I am trying to make my new Stealthburner toolhead, equipped with the FYSETC's SB CAN TH and UCAN. My voron 2.4 is using the Spider v2.2.
This is how my wiring setup is done: RPI4b > UCAN > SB CAN TH
I've done the make menuconfig and uploaded the firmware exactly as per https://wiki.fysetc.com/SB%20CAN%20ToolHead/. Next, I attempted to follow https://www.klipper3d.org/CANBUS.html but I found that I was unable to find the canbus_uuid.
I also attempted to follow https://github.com/Esoterical/voron_canbus, since I was out of resources but to no luck at all. To be sure, I inserted a can0 file into /etc/network/interfaces.d, but I still cannot get the can0 network up at all after running ifconfig.
