Manta M8P + CB1 + EBB SB2209 CAN V1.0 (RP2040) Setup Help..

[noble dome]

Im having some confusion with this whole CAN bus this. I have the OS running on my CB1 and now i need to flash the manta board as well as the SB2209 (RP2040) CAN board in the toolhead with Katapult and Klipper i think..?

Honestly i'm so confused with this whole CAN thing, does someone have a good guide for this specific setup? Every video has a different setup than mine and it does not help. Specifically the RP2040 chip variant.

I just bought this Formbot Voron 2.4 R2 Pro kit and i'm quite bummed at not being able to set up the CAN bus..

Im following this guide:
https://forum.vorondesign.com/threads/manta-m8p-btt-ebb-sb22xx-setup.1697/

When i get to flashing katapult to the EBB SB2209 RP2040 i get this error:

biqu@BTT-CB1:~/klipper$ sudo dfu-util -a 0 -D ~/katapult/out/katapult.bin --dfuse-address 0x08000000:force:leave -d 2e8a:0003

this is the guide you'll get here https://canbus.esoterical.online also if u do end have having questions you'd be better off asking in #can_and_usb_toolhead_boards i dont think many have canbus experience

The canbus boards usually have a USB option plus a boot switch.

Dfu is basically a mode that allows the board to be flashed

See page 27 for getting your canbus board into DFU mode for flashing

I bought the same kit and ran into the same roadblock. I ended up following MagicPheonix's guide (https://mpx.wiki/Firmware-Flash/flash-m8p-v1-ebb) as their kit also uses the M8P and EBB. Just bear in mind that the guide references the STM32 equipped EBB, not the RP2040 version that Formbot used, so you need to be sure to configure it accordingly. Otherwise the process is exactly the same.

The Manta M8P V2 guide on the site is better written, but just be aware that the pinouts on the M8P V2 are different from the V1 if you reference it.
