With regards to the camera problem, the printer seems to now happily print and show me a video at the same time without crashing on me after 10 hours or so.
I halved the resolution and I halved the FPS as well. Not the best image but good enough to see if it is worth worrying about it or let it continue. The AI also states all looks good so we will see where that ships strands. Maybe one day I will attempt a deliberate spaghetti monster and see if it picks it up.
With regards to your evaluation of the modifications of numerous sources, I believe they are remnants of the OS that was used as a base to build this machine, and partly left over from when the machine got changed to mainsail from fluidd.
I will yank my other SBC out of my unfinished project and attempt to build a klipper from scratch.
Not looking forward to it but probably the best way forwards and a good way to learn the hard way.
Thanks for your time again, I will close this thread now as solved.
If, or rather “when” I will run into trouble doing the new build, I will open a new discussion.
