Cannot get UUID

General Discussion

Basic Information:

Printer Model: Core XY
MCU / Printerboard: Manta 8P + EBB42
Host / SBC CB1
klippy.log

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

I have connected Manta 8P +CB1 with EBB42 and following the steps as mentioned in the video.

BTT EBB V1.0 CAN Setup Guide

But I am unable to get the UUID (refer video time 9:40)

biqu@bigtreetech-cb1:~/katapult/scripts$ python3 flash_can.py -q
ERROR:root:Flash Tool Error

During handling of the above exception, another exception occurred:

You had a look here? CAN Basics

Yes..I did..

Rather than a three year old video, I suggest that you follow the Esoterical guide:

It’s been kept up to date regarding the updates to the various host operating systems and Klipper.

I followed this but can get the board into CAN mode…

Is this correct config?

That’s what I use for my printer that uses a Manta M8P V2.0.

What steps did you go through to get to the point of loading Katapult/Klipper?

You should be starting with a freshly imaged SD Card and not one that you’ve been working with.

I am following steps from this https://canbus.esoterical.online/

Are you using a USB cable to flash katapult to the EBB42 ? Been a while since I changed my Idex to canbus but if I recall there is a button combination on the EBB boards to put them into flash mode. To flash my Octopus board I had to install the DFU jumper then remove it when done, not sure about the Manta.

I’m not sure what OS the CB1 uses but there are set up differences in newer OS (IE: Bookworm vs Bullseye) due to systemd.

Order is important, do katapult first before since it’s the bootloader.

Sorry for delay in reply.

I referred the website https://canbus.esoterical.online/ and successfully installed OS image and other stuff on Manta 8P V2 + CB1 + EBB42 V1.2.

Thanks all for the help you provided.
