I have searched the forums, but found no solution for me. I found many similar issues, but the topics were all closed.
I have a new LightBurn 140 degree camera. The camera works fine in the Windows Camera app, and shows in the drop-down list of LightBurn camera, however I am unable to select the camera to proceed with lens calibration. There is no image displayed in the viewing window. I am using the provided USB cable (about 8’) and have tried each USB port on my PC.
Windows 10
LightBurn 0.9.16
140 Degree LightBurn camera in mount.
I appreciate the quick response. I do not have a 3rd party anitvirus installed, just Windows Defender. It does not appear to be causing the problem; I did disable all the firewalls and re-attempted without success. I did not see any other settings that might block camera access.
Windows- Settings- Privacy- Camera set to allow apps access to camera. LightBurn IS NOT listed in the Apps list. I don’t know how to add it??
I attempted to run LightBurn in compatibility mode for Windows 8 with “recommended settings” but had same results; no image.
We’ve been without power for 4 days (now restored), so things are slower than usual.
In LightBurn, please do the following for me:
Select ‘None’ for the camera
Go to Help > Enable debug logging
Select the LightBurn camera
Wait a moment for it to try to connect (count to 10)
Quit LightBurn
You’ll find a file called LightBurnLog.txt in your Documents folder. Post it here, or email it to support@lightburnsoftware and include a link to this thread so I know what it’s for.
I have had the same issue with same camera just got in. did everything you asked above and didnt work as well. Here is my log.txt file

I’m having the same issue. I haven’t been able to use my laser for a month or so, and reset my computer. Previously the camera and everything worked. The computer makes the notification sound when the camera is plugged in, and when I reinstalled Lightburn it gave the message “setting up lightburn camera” during install

Copy it over the file with the same name in your LightBurn program folder (C:\Program Files\LightBurn)
Delete your existing log file
Run the same test again
The above replacement basically just tries to apply get the stream settings a couple times in a row, with a small delay in between, in case the system is slow and the camera isn’t streaming yet.
Can you folks also reply with what kind of computer you have? CPU / Speed / Memory? I’m trying to understand if this happens because the computer is slow, or there’s a driver issue, or something else.

Haven’t had any problems running any of other programs like CS6 photoshop, Adobe illustrator, or corel draw all at same time.
Hmm - This doesn’t look like the new library is getting used, so it’s possible I botched uploading it. It’s late, so I’ll take another crack at this tomorrow.
