3. How to add webcam to Klipper?

It is anticipated that you have already set up Klipper on your 3D printer. Webcams are naturally supported by both interfaces without the requirement for additional installation files. We’ll describe setting up USB webcams for Mainsail OS and FluiddPi pictures.

Configuration of the FluiddPi USB webcam

  1. Sign in to your Fluidd account after connecting the USB webcam to your Raspberry Pi.
  2. Navigate to the camera section of the settings window.
  3. Add a webcam and give it a name.

Klipper, one of the few 3D printing firmware, offers native compatibility for an external camera that you might utilize to monitor the workflow of your printer. You can combine a webcam to Klipper for viewing your printing progress from the internet interface, the Raspberry Pi may be readily connected with a camera.

However, as Klipper is the most recent firmware, there aren’t many sources or guides that go over all of its features. If you’re a learner or new user, you may find it tricky to set up and install a webcam on the Klipper 3D printer.
