Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible

WRITE HERE

  • OctoPrint 1.9.3
  • Python 3.9.2
  • OctoPi* 1.0.0cam (build 2023.10.09.154319)
2

I assume you have tried rebooting the Pi after plugging in the Pi camera?

3

yes of cause, First Thing I try

4

Problem is still there, when I do a backup, and fresh intstall an replay the backup, only when I make a complete new install I see the webcam image...

5

If it's impacted by the OctoPrint backup, my guess is that you have the stream URL configured wrong in the backup and it's overwriting whatever the default (correct) one is.

For the new camera stack OctoPi image, use:

  • Stream URL: /webcam/?action=stream
  • Snapshot URL: http://127.0.0.1:8080/?action=snapshot

Try it and see what happens.
