Apologies for this, but I was on my mobile when I replied to the first post here, and didn’t see that your honeycomb is visible - That’s the issue, and it’s the most common problem we see - it’s the first bullet point here: The camera doesn't find the lens calibration pattern (no pattern found)
It’s also specifically called out in the documentation here:
https://lightburnsoftware.github.io/NewDocs/UsingACamera.html#the-camera-lens-calibration-wizard
The code is looking for circles, and the honeycomb presents a TON of them - it will eventually finish, but not in any reasonable amount of time. Cover the honeycomb with paper, cardboard, a towel, bedsheet, etc and that will fix it.
