I noticed that the new version of the software has added the option “Camera is mounted to the laser head”. Regarding this feature, I would like to know the following:
The easiest thing for all of us will be to start with the search function. I see that there are over 50 posts regarding this topic 
Okay，I’ll go search and take a look first.
I have looked through previous posts and completed “Calibrate Camera Lens” &“Calibrate Camera Alignment” successfully. However, I am unsure of what to do next.
I clicked “Update Overlay” and the laser head returned to its original position, but nothing else happened. I would like to know what steps to take next.
I don’t have a head-mounted camera but as I understand it, once you push “Update Overlay” the camera should move to several locations taking enough pictures as necessary to be able to create a composite image of the bed.
If that’s not happening I suspect something didn’t go right in the camera setup process.
Yes, according to what I’ve read in the posts, it should take multiple shots and then stitch the images together, but that didn’t happen in my case. I’m not sure where I went wrong… 
It appears that LightBurn “has a problem” with this feature at the moment.
The last time I tried it, it worked as a “position retrieval” tool for me. When the camera was adjusted and corrected for x and y offset, it could be used fine for cut and print or precision positioning of the laser head. As I said, it’s been a while since I’ve used this function with success, the last time I tried it didn’t work either and I blamed my Linux version for it, I actually end up at the same point as you.
It surprises me how few use this head mounted camera option.
I don’t know how high this issue is on the work list from the LightBurn folks, if we’re lucky there will at least be a comment from Oz and friends.
When you try to update the overlay, are you selecting an individual shape, like a rectangle? The laser/camera should move to capture an overlay of only that specific area. If you have nothing selected, it will attempt to produce an overlay of your entire workspace. Currently, if the offset between the camera and laser head makes that impossible, the process may stall out.
I can confirm this feature is still under development- I discussed it with Oz recently- although I’m not sure where it sits on the ever-growing priority list. 
No, it doesn’t make it past the last step of the setup, just as @Hanmy describes it.
And I can confirm that it has worked once, but it was just at the beginning of the “implementation” of this interesting feature.
Is this installation method intended to assist with the “Print and Cut” functionality?
@bernd.dk - that seems to be slightly different behavior than Hanmy is describing (the alignment finishes, but the overlay creation process isn’t working). What’s happening at the last step of setup for you?
@Hanmy - yes, that is a possible use for this feature, although Print & Cut can currently be used without any camera assistance.
After I have the line square snapped to the nearest intersections of the template grid I jog as prescribed to see/judge the accuracy of the settings. Then the process is finished, but when I want to update the workspace itself, i.e. what the camera can see, the laser head moves to its home position without an image appearing on the work surface (but a live view is there in the camera settings). If I position the laser head in the middle of the machine bed and press “update overview” the laser always goes home.
I don’t rule out an “Error-47”, but then we can try to look at the “calibrate camera alignment” instruction. maybe I’m reading it wrong.
I’ll add a few pictures, let me know if I can contribute anything else.
Thanks - this is being looked into.
