Camera Calibration not capturing the polka dot pattern

LightBurn Software Questions Tips and Tricks
, , ,
1

I have purchased a Creality Falcon 2 Pro with a 40W laser. I am running Lightburn 2.1.04 on the 30 day free trial on my HP Spectre with Windows 11 Home.
Lightburn has found the camera and I am trying to calibrate it using the provided polka dot pattern.
Lightburn does not offer “Capture” in the dialogue box.
I have tried changing the capture system in General settings - no success.
What have I missed?

You need to use the AprilTags calibration card linked on this docs page:

The polka dots pattern is not used anymore. Some manufacturers still ship this with some devices, because they use it in their software, but the AprilTags are way more accurate.
