Arducam 16 MP Autofocus Camera 2020 Extrusion Mount for Voron Trident

This is a 2020 extrusion mount for a 16 MP Arducam Autofocus camera customized for my Voron Trident. Mount it in this order:

1. Use an M3x8 SHCS and an M3 hammerhead nut to attach the 2020_extrusion_mount to the extrusion. 
2. Use an M5x12 BHCS (or SHCS) and an M5 nut to attach the camera_case_bracket to the 2020_extrusion_mount. 
3. Use M3x6 screws to attach the camera_case_bracket to the arducam_16mp_case.
4. Thread the cable through the arducam_16mp_case, clip it in to the arducam, and then route the cable down the side of the 2020 extrusion through the cable channels to your raspberry pi. I used this pi camera extension cable.

To get your camera up and running,

1. Follow the Arducam quick start guide 
2. Make sure you can run commands like this and get an picture out: libcamera-still -t 3000 --autofocus-range normal --autofocus-mode continuous -n -o test.jpg
3. Install Crowsnest
4. Setup your crowsnest.conf:

[cam DEFAULT]
mode: multi
port: 8080
enable_rtsp: false
device: /base/soc/i2c0mux/i2c@1/imx519@1a # got this from the log file
max_fps: 10 #30
resolution: 4656x3496 #1920x1080
v4l2ctl: AfMode=2                         # Add v4l2-ctl parameters to setup your camera, see Log what your cam is capable of.
custom_flags: --camera-type=libcamera --camera-options=autofocus-range=normal

NOTE: If you run vcgencmd get_camera and get 0 supported/detected cameras, you may need to enable legacy camera support on your pi:

sudo raspi-config nonint do_legacy 0
sudo reboot
