Camera Calibration Issue - Black Image on Capture (Preview Works)

LightBurn Hardware Compatibility Cameras
1

Hi everyone,

I’m encountering an issue with the camera calibration functions in LightBurn. While the camera preview works perfectly, as soon as I try to use the calibration features, I only get a black image during capture. This is exactly the same problem as described in this thread from @pnevma.

I’m using versions 1.7.00 and 1.7.04, where this issue consistently occurs. Interestingly, this problem does not seem to happen in version 1.6.03.

As someone trying to evaluate the software during the 30-day trial, it’s quite challenging to fully test the functionality with this kind of issue.

Has anyone found a workaround for this, or is this something the team is aware of? Any advice or updates would be greatly appreciated!

Thanks in advance!

The person in the thread you linked had no problem calibrating the camera but encountered a black image when capturing the first image for the Alignment Wizard.

If that’s what is happening for you, I’d appreciate it if you could collect more info for our troubleshooting please;

In version 1.7.04 capture the black alignment image again while the debug log is enabled;

-turn on the debug mode (Help>Enable Debug Log).

-Start the Laser Tools> Calibrate Camera Alignment wizard

-Click on ‘Capture Image’

-Presumably at this point you get the black image, take a screenshot of that and then ‘Cancel’ and turn off the debug mode (select Help>Enable Debug Log again).

-Look in your Documents folder for the debug log ‘LightBurnLog.txt’, rename it to LightBurnLog_black1704.txt

Install LightBurn 1.6.03 and complete the alignment;

-Turn on the debug mode again (Help>Enable Debug Log).

-Go to Laser Tools> and Calibrate Camera Alignment.

-When the alignment is finished, turn off the debug mode (select Help>Enable Debug Log again)

-Look in your Documents folder for the debug log ‘LightBurnLog.txt’, rename it to LightBurnLog_good1603.txt

Try using the ‘Camera Control’ window to ‘Update Overlay’, everything should be working fine? If so, right-click on the image in the Camera Control Window and ‘Export Camera Settings’, save this as something like ‘CameraSettings_Good1603.lbcm’ file.

Close LightBurn 1.6.03 and re-install the 1.7.04 version update;

The camera should still be working fine, since the camera settings will have remained attached to the same device which is not changed during the program update.

Please email support with a link to this forum topic, the two debug files, the screenshot, and paste in your support data (Help > Generate Support Data ).
