Camera feed cuts after a few seconds

LightBurn Hardware Compatibility Cameras

I just recently ran in to this issue, and can’t seem to find an obvious solution—unless I’m overlooking something. I use a Lasermatic MK2 on a Mac Mini M2. I recently updated my OS to 15.3.2, and Lightburn to 1.7.08.

The camera works fine for a few seconds after startup. If I swap camera to “None”, and then back again to “HDR Camera” the feed comes back momentarily before cutting again. I thought it might be related to other apps fighting for camera access—but I disabled the camera access for all apps except Lightburn.

Any help would be greatly appreciated.

Can you try if the camera keeps working when you use MacOS PhotoBooth?

You would not be the only one experiencing USB issues related to Sequoia. See if resetting NVRAM and PRAM helps:

I have been having similar issues with camera setup. All permissions have been granted and photo booth is open during the session.
Hardware/Software

  • MacBook Pro M1 chip
  • OS Sequoia 15.4
  • Lightburn 1.7.08

I am able to live view the camera, however when trying to capture an image in the lens calibration the following occurs:

  • click capture image - says image can not be found
  • click capture image - image button grays out and the wizard freezes

I have been able to “random successfully” make it to the alignment wizard only to have the following:

  • Click capture image - all black image is captured
  • Click capture image - nothing happens
  • Click capture image - button grays out and wizard freezes

Has anyone figured out how to successfully complete this on a Mac? Its super frustrating to have it make to 90% completion and stall out.

While you are using LightBurn? This would interfere with the camera usage, only one app can access the camera at a time, usually.

I have tried it both ways and still have the same outcome…having PhotoBooth open was a suggested work around from another forum.

@JediJeremy I see that you are the camera expert here! Any ideas on what might be going on? Currently when I go to calibrate the camera lens the following happens:

  • Click capture image and the button grays out and the application hangs
  • Click capture image and says that the pattern can not be found (it shows cleanly in the view)
  • Randomly will successfully make it to calibrate alignment
  • After running the laser file, capturing the image hangs and I can never get past this point.
    Any assistance on how to successfully install the camera?
