Connect Raspberry Pi camera to Prusa Connect

I had an old Octopi setup that I wanted to repurpose to work with my Prusa MK4. This repo allows you to reuse the raspberry pi camera you have setup.

Setup

Environment variables

Update all environment variables in config.env. You will need FINGERPRINT and TOKEN from Prusa Connect. You can get the fingerprint by adding a new camera and looking at the request headers using Chrome Developer Tools (or similar).

Running

poetry install
nohup poetry run picam.py &

Run as a service (linux)

Edit file

$ sudo vim /etc/systemd/system/prusa_picam.service

and include

[Unit]
Description=Prusa PiCam service
After=multi-user.target
[Service]
Type=simple
Restart=always
EnvironmentFile=/home/<username>/<path>/prusa-connect-rpi/config.env
ExecStart=/usr/bin/python3 /home/<username>/<path>/prusa-connect-rpi/picam.py
[Install]
WantedBy=multi-user.target

Note the python directory and path to file should be adjusted as needed. Environment file config.env should be edited to remove "export " prefix on each line. Reload the daemon and start the service

$ sudo systemctl daemon-reload
$ sudo systemctl enable prusa_picam.service
$ sudo systemctl start prusa_picam.service

FAQ

I already have octopi running and don't want to shut down the service, can I reuse the web stream?

Yes, you can set the STREAM_URL in config.env to the stream. In my case it is http://octopi.local/webcam/?action=stream
