DISCLAIMER

THIS TUTORIAL WILL NOT WORK WITH RASPBERRY PI OS "BUSTER" MAKE SURE YOU'RE RUNNING RASPBERRY PI OS "BULLSEYE" THIS ALSO WILL NOT WORK WITH UBUNTU OR OTHER DISTRO

THIS WILL WORK WITH SETUP INSTALLED BY KIAUH IF YOU'RE USING OTHER METHOD OF INSTALLING KLIPPER AND IT'S COMPONENTS SOME OF THIS MIGHT NOT APPLY TO YOU

this tutorial will work with Arducam 16mp AF camera I'm not sure about other model, your milage may vary

PART I, INSTALL ARDUCAM DRIVER

if you're using other model you might want to follow a tuorial for that model if you're running the same model as I do you can follow if you already installed the nessary packages and driver skip to PART II

1. cd back to your home directory

   cd ~

2. Download arducam tool for installing packages and add execute permission to it

   wget -O install_pivariety_pkgs.sh https://github.com/ArduCAM/Arducam-Pivariety-V4L2-Driver/releases/download/install_script/install_pivariety_pkgs.sh
   chmod +x install_pivariety_pkgs.sh

3. install IMX519 Driver after this process it will ask you to reboot, reboot before continueing

   ./install_pivariety_pkgs.sh -p imx519_kernel_driver

4. install libcamera packages

   ./install_pivariety_pkgs.sh -p libcamera_dev
   ./install_pivariety_pkgs.sh -p libcamera_apps

5. check if your raspberry pi detects the camera

   ls /dev/video*

   you should see video0 and video1 if not reseat your camera cable if that still dosent work I recomend rebooting the pi if that still dosen't help get in touch with Arducam guys so they can try to help you!

PART II, configure

1. get MJPG-Streamer working I will not show this process but you can install it using kiauh
2. download MJPEG-Streamer libcamera module from this repo

   wget https://github.com/ChokunPlayZ/arducam-libcamera-klippper/raw/main/input_libcamera.so

3. copy the module into your MJPEG-Streamer directory

   mv ./input_libcamera.so ./mjpg-streamer/input_libcamera.so

4. download webcamd file from this url to your computer

   https://github.com/ChokunPlayZ/arducam-libcamera-klippper/raw/main/webcamd

5. open the file and edit the following setting using any text editor edit line 8 and 9 with the username you're loggin in with in many case it will be pi you can also edit focus setting, since autofocus is not currenly not supported you have to set the value manually
6. backup the old webcamd file with this command

   sudo mv /usr/local/bin/webcamd /usr/local/bin/webcamd.bak

7. copy the contents of the webcamd you downloaded to your computer, make sure that you have put in the correct info
8. create a new webcamd file using

   sudo nano /usr/local/bin/webcamd

9. paste the new webcamd file content into the nano window use RIGHT CLICK for windows command prompt and putty use CTRL + V for tabby terminal
   10. save webcamd file just CTRL + X then Y then ENTER
   11. Add execute permission to webcamd file

       sudo chmod +x /usr/local/bin/webcamd

   12. add following content to your webcam.txt config file

       camera_libcamera_options="-f 30 -r 640x480"

10. change this option in your webcam.txt file

    camera="libcamera"

    14. restart webcamd service this process can be done in many way you can just run

        sudo systemctl restart webcamd

        to restart the service or you can reboot the pi I would suggest rebooting it

        Now you're set!
