Camera Preview Works - Calibration Blank

[ronselljr (Ron)]

Anyone having issues with the camera in LightBurn? I have LightBurn Pro 2.0.02 installed. I had to re calibrate my camera but when I run the camera alignment I get a blank screen. I uninstalled, restarted and changed the USB cable. I ran the calibration wizard multiple time with the same results. Laser: 1Laser XRF

I have the same issue with the Falcon2 Pro 40W.

@ronselljr @RonPdm let us know if this helps:

If you’re seeing the black overlay image, it may be due to using an old Camera Lens correction profile in version 2.0.

Please follow the instructions for camera calibration with Tracking to see if it solves it for you too: Calibrate Camera Lens (Labs) - LightBurn Documentation

This feature is still in testing (Labs feature) but is currently the most precise way to calibrate your camera. It’s only accessible with a right click on the “Camera” window:

After this, perform another Camera Alignment as usual: Calibrate Camera Alignment - LightBurn Documentation

Hi Aaron, thanks for the tip. The workaround was successful, the camera works.
However, with the default settings, the actual calibration using the ‘classic’ method is inaccurate, especially on the edge. So the camera is not really usable.

That sounds promising! Thank you for the feedback.

@RonPdm

By ‘classic’ method, do you mean the old way of calibrating the lens with the circles pattern?

Yes, this is why the lens calibration with Tracking will become the default method.

It’s important to know that the Camera Alignment can only be accurate at the height at which the Alignment was performed.
