Welcome to Prusa-Connect-Camera-Script

logo

This project aims to make it easier to use any camera to be used as Prusa Connect camera.

Features

  • allows to read images from CSI cameras, USB cameras, RTSP streams, still images...
  • do not send pictures if the printer is offline
  • store data in memory to prevent MicroSD wear out
  • verbose error messages to see if the image capture works
  • ability to run multiple cameras in separate instances
  • ability to run in docker containers (multi-platform multi-arch)

Architecture

sequenceDiagram script->>script: initial checks script->>script: start loop script->>camera_command: Call camera command camera_command->>image_on_disk: camera command writes image to disk image_on_disk->>script: script checks image from disk if exits etc script->>script: show errors if image_on_disk is missing script->>curl: run curl to post image to Prusa Connect API (pass image_on_disk) curl->>image_on_disk: curl reads image from disk curl->>PrusaConnect: send image to Prusa Connect PrusaConnect->>curl: return response code / messages script->>script: sleep + end loop

Known limitations

  • this script performs processing of the single camera, if you need more cameras then just create multiple copies with different settings (see below)

  • Rpi Zero W or older devices may have CPU limitations to process remote streams or multiple cameras at once

  • I was not able to test EVERY setting so this may still have some bugs

  • Prusa Connect will not show camera image if the printer is not alive, this is Prusa Connect limitation.
  • default settings are quire generic and thus low camera quality, you need to adjust them, see advanced configuration at the end
