Katapult Update Voron 2.4

[inland slate]

Hello, I am trying to update my Katapult with the toolhead (SB2209 RP2040) and MCU. It seems the toolhead was updated successfully, but the MCU wasn't. I'm following @languid remnant guide step by step: https://canbus.esoterical.online/Updating.html.

Katapult Update Voron 2.4

It seems that I have installed successfully MCU

But Printer doesn't start at all

[thin lance]

following the esoterical canbus guide?

[inland slate]

yes

[thin lance]

File downloaded successfully means that it is working like it's supposed to be, ignore the errors after that

[thin lance]

which step are you on?

[inland slate]

The next one

I get the Id

and after that this one => https://canbus.esoterical.online/mainboard_flashing.html#installing-usb-can-bridge-klipper

And now I am here

??

I also have U2C installed.

[thin lance]

so you are using usb to can bridge?

[thin lance]

Choose one: usb to can bridge or u2c

[inland slate]

U2C

I am not use USB

[thin lance]

but... you cant use DFU util with a rp2040 based can board

im fairly certain that you just flashed your mainboard with usb to can bridge

[inland slate]

So that's wrong then. Which step should I follow for U2C

https://canbus.esoterical.online/can_adapter/BigTreeTech U2C v2.1/README.html

I have this one

[thin lance]

you aren't supposed to be following the mainboard flashing with u2c

[inland slate]

That understand it right now. So, I should skip this step

[thin lance]

flash klipper on your mainboard with the regular settings

not usb to canbridge

[inland slate]

like that?

[thin lance]

and then do this https://canbus.esoterical.online/toolhead_flashing.html

[thin lance]

which mobo?

[inland slate]

STM32F446

[thin lance]

that's the chip, need the motherboard

name

[inland slate]

Octopus

And I will use this one

correct?

[thin lance]

which octopus?

[thin lance]

yes

but I recommend flashing your octopus with the correct settings first

[inland slate]

BIGTREETECH Octopus V1.1

[inland slate]

are not correct?

I am here https://canbus.esoterical.online/toolhead_flashing.html#katapult-is-now-installed

And I got the UUID from the toolhead

[thin lance]

those are the settings for usb to can bridge, which you will not be using since you have a u2c. Use this instead

To use this config, the firmware should be compiled for the STM32F446 with a "32KiB bootloader"

Enable "extra low-level configuration options" and select the "12MHz crystal" as clock reference

[inland slate]

I have already selected that

what about those ?

[thin lance]

hold on, the BTT config is incomplete. Lemme get the actual one.

[inland slate]

That's the correct ones?

[thin lance]

yup correct, was just boutta send that

[inland slate]

after make?

[thin lance]

if you bought the u2c recently, they already come preflashed (like mine did)

[thin lance]

flash it

[inland slate]

ython3 ~/katapult/scripts/flashtool.py -f ~/klipper/out/klipper.bin -d /dev/serial/by-id/usb-katapult_your_board_id

[thin lance]

not sure about the octopus but generally there is a micro sd port

[inland slate]

using the above?

[inland slate]

ok

I flashed it. Shoud I see now the MCU into The System Loads?

I just followed and this one https://canbus.esoterical.online/toolhead_flashing.html#rp2040-based-boards

[thin lance]

did you add the new mcu serial in the printer.cfg?

[inland slate]

This one?

[thin lance]

yes

[inland slate]

I have already added

But still remain the issue..

[thin lance]

it might have changed. also, run lsusb

[thin lance]

and ls /dev/serial/by-id/

[inland slate]

It's not working

[inland slate]

FYI: it works

Thanks @thin lance 🙏
