# deb http://raspbian.raspberrypi.org/raspbian/ bullseye main contrib non-free rpi
deb http://raspbian.mirror.ac.za/raspbian/ bullseye main contrib non-free rpi

Update

apt clean all
apt update -y
apt dist-upgrade -y

Better editor

LANGUAGE=en_US.UTF-8
LC_ALL=en_US.UTF-8
LANG=en_US.UTF-8
LC_CTYPE=en_US.UTF-8

Reboot

reboot now

Flash candlelight_FW

mkdir ~/firmwares
cd ~/firmwares
git clone https://github.com/candle-usb/candleLight_fw.git
cd candleLight_fw

Follow build instructions

Add Can network adapter

sudo wget 'https://raw.githubusercontent.com/jvandervyver/Voron-2.4can-Config/main/downloads/can0.config' -O '/etc/network/interfaces.d/can0'
sudo reboot now

Flash CanBoot

mkdir ~/firmwares
cd ~/firmwares
git clone https://github.com/Arksine/CanBoot.git
make clean
make menuconfig

Follow the rest of the insturctions for flashing CanBoot in DFU mode.

Klipper firmware setup

Setup firmware build repos

mkdir ~/firmwares
cd ~/firmwares

git clone https://github.com/Klipper3d/klipper.git

Setup menu config for Raspberry Pi

cd ~/firmwares/klipper
make clean KCONFIG_CONFIG=config.rpi
make menuconfig KCONFIG_CONFIG=config.rpi
make flash KCONFIG_CONFIG=config.rpi

sudo wget 'https://raw.githubusercontent.com/jvandervyver/Voron-2.4can-Config/main/downloads/klipper-mcu.service' -O '/etc/systemd/system/klipper-mcu.service'
sudo systemctl enable klipper-mcu.service
sudo service klipper-mcu start

Setup menu config for Octopus F446

cd ~/firmwares/klipper
make clean KCONFIG_CONFIG=config.octopus_f446
make menuconfig KCONFIG_CONFIG=config.octopus_f446

Setup menu config for EBB36

cd ~/firmwares/klipper
make clean KCONFIG_CONFIG=config.ebb_36
make menuconfig KCONFIG_CONFIG=config.ebb_36

Install config

cd ~
git clone https://github.com/jvandervyver/Voron-2.4can-Config.git

ln -s ~/Voron-2.4can-Config/config/klippy.conf ~/printer_data/config/klippy.conf
ln -s ~/Voron-2.4can-Config/config/printer ~/printer_data/config/printer

mkdir ~/printer_data/config/macros
ln -s ~/moonraker-timelapse/klipper_macro ~/printer_data/config/macros/timelapse

mkdir ~/printer_data/config/macros/mainsail
ln -s ~/mainsail-config/mainsail.cfg ~/printer_data/config/macros/mainsail/mainsail.cfg

rm ~/printer_data/config/timelapse.cfg
rm ~/printer_data/config/mainsail.cfg

Update klipper environment to use klippy.conf

vi ~/printer_data/systemd/klipper.env

Install Voron theme

curl 'https://raw.githubusercontent.com/jvandervyver/Voron-2.4can-Config/main/scripts/install_theme.sh' | bash

Webcam using WebRTC

In order to get WebRTC working as-of 7 May 2023 you need to switch over to the develop branch of crowsnest.

cd ~/crowsnest
sudo make uninstall
# Reboot

git reset --hard
git checkout develop
git branch --set-upstream-to=origin/develop develop
git pull
git reset --hard
make install

sudo vi /boot/config.txt

There may be multiple entries containing camera_auto_detect. Remove all but one and set it to camera_auto_detect=1. This is required to load the overlays for cameras.

crownest.conf is going to be updated, but for the Raspberry Pi v2 camera the following works well:

[cam 1]
mode: camera-streamer                      # ustreamer - Provides mjpg and snapshots. (All devices)
enable_rtsp: false                         # If camera-streamer is used, this enables also usage of an rtsp server
rtsp_port: 8554                            # Set different ports for each device!
port: 8080                                 # HTTP/MJPG Stream/Snapshot Port
device: /base/soc/i2c0mux/i2c@1/imx219@10  # See Log for available ...
resolution: 1280x720                       # widthxheight format
max_fps: 30                                # If Hardware Supports this it will be forced, otherwise ignored/coerced.

If it doesn't work, try debugging using log_level: debug which will contain the camera-streamer logs

Next setup mainsail use WebRTC:
