Describe your issue:
Let’s see another day plagued with failures, it’s the same request as always, but although I was very interested in installing a Canboard connected by CAN, everything has been failures, the closest I’ve been is a Mellow SHT42, but with which I could NOT print not a single layer…
I have been following another guide, which are the components I want to install:
Following the steps of the video well, but when I get to minute 12 approx, I have already flashed, wired and configured everything… and restarted… I send the script to find out the UUID, but I get the same error as other times .
The truth is that I am getting tired of NOT being able to use the printer, I had high hopes for the connection with the toolboard by CAN, but I am losing them.
When I get to minute 12 or so, and send:
~/klippy-env/bin/python ~/klipper/scripts/canbus_query.py can0,
this bug
pi@ratos:~ $ ~/klippy-env/bin/python ~/klipper/scripts/canbus_query.py can0

I could solve this error previously, with a script that you passed me through the forum, this one:
sudo ip link set up can0 type can bitrate 500000
But having the Can Board configured like this, shortly after starting to print, the printing fails, a time out error, and if you looked at the Ifconfig, you could see many packages with errors…
This couple of days I have tried the combination: Octopus Pro + U2C + EBB42… the three elements of Bigtreetch. As a note to review is that I have flashed the Candelight firmware in the U2C.
and I followed another video guide, this time:
Another point is that if I command “ifconfig”, the CAN0 network interface does not appear.
For it to appear, I have to send a script…
A few days ago, I was very happy because I got it to be, another combination:
Octopus Pro - Utoc 1 - SHT 42
But the joy didn’t last long, since shortly after, in the first printing job, it stopped due to timeouts…
That’s partly why I decided to change to the EBB42… but nothing.
Does anyone have an idea what I may be doing wrong?
This time there is something new… before, although the script failed, it sent this to the console:
sudo ip link set up can0 type can bitrate 500000
and at least the network interface CAN0 appeared with ifconfig, this time, if I send it the script, the response is:
Cannot find device “can0”
So I don’t know very well what I can do, I have also seen that there is a firmware update, which I think modifies something about the CANBUS.
