Additional Camera¶
For Simple AF for RPi you can setup multiple cameras via crowsnest. However for K1 Series (which includes K1, K1M, K1SE, K1C, Ender 5 Max and Ender 3 V3 KE) you cannot run more than one camera on the printer itself, the webcam service only supports a single camera because trying to run more than one camera is a really bad idea on this hardware.
The solution on K1 Series for additional cameras is to setup a separate RPi or Orange Pi (or the like) on the same network as your printer and install crowsnest. and then update /usr/data/printer_data/config/webcam.conf with that camera so that fluidd and mainsail will load it, but the printer itself will have nothing to do with this.
Get yourself a raspberry pi or an orange pi zero and get some kind of debian distribution installed, the following instructions will assume debian.
Install Crowsnest¶
We use crowsnest on Simple AF for RPi, I am sure there are different options you can try but I know crowsnest so I will document that, lets get it installed first.
sudo apt-get update
sudo apt-get --yes install make
git clone https://github.com/mainsail-crew/crowsnest.git ~/crowsnest
cd crowsnest/
sudo CROWSNEST_UNATTENDED=1 CROWSNEST_ADD_CROWSNEST_MOONRAKER=0 make install
Lets start it so it writes its default config which we will need next:
The config file for crowsnest will be located at ~/printer_data/config/crowsnest.conf
The config file will look something like:
[crowsnest]
log_path: /home/orangepi/printer_data/logs/crowsnest.log
log_level: verbose # Valid Options are quiet/verbose/debug
delete_log: false # Deletes log on every restart, if set to true
no_proxy: false # If set to true, no reverse proxy is required. Only change this, if you know what you are doing.
[cam 1]
mode: ustreamer # ustreamer - Provides MJPG and snapshots. (All devices)
# camera-streamer - Provides WebRTC, MJPG and snapshots. (only RPiOS + RPi 0/1/2/3/4)
enable_rtsp: false # If camera-streamer is used, this also enables usage of an RTSP server
rtsp_port: 8554 # Set different ports for each device!
port: 8080 # HTTP/MJPG stream/snapshot port
device: /dev/video0 # See log for available devices
resolution: 640x480 # <width>x<height> format
max_fps: 15 # If hardware supports it, it will be forced, otherwise ignored/coerced.
#custom_flags: # You can run the stream services with custom flags.
#v4l2ctl: # Add v4l2-ctl parameters to setup your camera, see log for your camera capabilities.
You must change the no_proxy from false to true because otherwise the camera service is not available on the wifi or ethernet interface.
And additionally its possible you will need to change the device: /dev/video0 to something else than the default and to find out what devices are
available you can use a crowsnest tool:
Warning
According to the crowsnest project, its always preferable to use full paths, especially in Mutlicam setups using /dev/video* will lead to errors or unexpected behaviours.

Note
After you have changed the no_proxy and potentially the device you must restart crowsnest with sudo systemctl restart crowsnest
Enable Camera in moonraker¶
You can just add an additional camera to the webcam.conf located in the config directory which you can edit via fluidd or mainsail and then just
restart moonraker from the services menu, the additional config might look like:
[webcam additional]
location: rpi
enabled: True
service: mjpegstreamer
flip_horizontal: False
flip_vertical: False
rotation: 0
target_fps: 10
target_fps_idle: 5
stream_url: /webcam/?action=stream
snapshot_url: /webcam/?action=snapshot
stream_url: http://X.X.X.X:8080/?action=stream
snapshot_url: http://X.X.X.X:8080/?action=snapshot
Where X.X.X.X would be replaced with the ip address of your RPi running crowsnest!
