prusa-cam

I set up a Logitech C920 webcam inside my Prusa enclosure to be able to monitor my prints using Prusa Connect. prusa-cam is a Bash script that POSTs snapshots from your webcam to the Prusa Connect API in 10 second intervals, which I believe is the minimum time generally allowed by Prusa. It only sends snapshots when your printer is online and actively printing. It pings your printer locally and runs as a systemd service, and logs if things are successful or not, resetting states if failures occur.

Dependencies

• curl
• jq
• v4l2-ctl
• ffmpeg

Setup

• Copy prusa-cam to somewhere like "$HOME/.local/bin/"
• Copy the systemd service to "$HOME/.config/systemd/user/"
• Edit the systemd service with the full path to the script
• Copy env.example to "$HOME/.config/prusa-cam/env"
• Edit the file with your settings
  • Get your printer API key from your printer (PrusaLink API key)
  • Get your camera name from v4l2-ctl --list-devices
  • Generate a fingerprint with something like pwgen 32 1 | base64
  • Get your token from Prusa Connect > Camera > Other cameras
• Run prusa-cam, ensure you're getting successes
  • Note: prusa-cam will only start POSTing snapshots if your printer is actively printing
  • prusa-cam will let you know if one of the critical dependencies is missing, or if your config is missing required fields
• Run systemctl --user enable --now prusa-cam
