Error configuring printer

Hello! I have been battling my printer for a while before my Voron stealth burner fully arrives and I keep having trouble setting up my configs. I keep getting this error. After asking ChatGPT, it states that my config has an invalid can UUID, but nothing more. I don’t have much experience with Klipper, but my first time going through this worked flawlessly so I don’t know what happened.

Any help is appreciated!

First, it looks like you edited the klippy.log file that you posted on PasteBIn. you should provide the complete file.

Second, you were told to attach the klippy.log to your post. Putting four files on Pastebin won’t help.

Third, and the biggest question I have, why would you go to ChatGPT before asking for help here?

Please reply with you unedited klippy.log attached to the reply.

So sorry about that, I put it into Chat GPT because they are usually really good with summing things up. I am also working out the ins and outs of this website, so I figured I would need a Pastebin instead of linking the stuff here lol.

You have three MCU statements for the CB1 host in your printer.cfg:

[mcu CB1]
serial = 7b677487e401

[mcu cb1]
serial = /tmp/klipper_host_mcu

[mcu]
canbus_uuid = 7b677487e401

Is there a toolhead controller (connected via CAN)? You have:

[mcu EBBCan]
serial = /dev/serial/by-id/usb-Klipper_stm32h723xx_360020001951313236343430-if00

Which doesn’t make any sense.

I deleted the extra mcu cb1 and everything is running now! thank you so much.
