Camera sees entire bed for calibration, then only part of it for the overlay

[thestip (Matt)]

Hey all,

I’ve got one of those generic 5MP USB cameras (OV5648) on my laser mounted to the lid. I’ve run the calibration and alignment a few times without error, but the camera overlay is always skewed and missing the top of the platform. The camera clearly sees the entire bed; I placed the pattern at the edges of the work surface, so it seems like the issue is with lightburn.

I’ve done the calibration/alignment process as a normal lens and as a fisheye and there’s no difference.

(The image is correct, I’m burning something onto the back)

Thanks in advance for any suggestions!

I’m having a similar problem. I have a new Logitech camera and not only does it only show part of the image (as above) but it’s shifted to the left about 1/2 of the screen.

I have almost the same issue with the LB 4k camera. during calibrating the camera is fine, but in overlay it isn’t correct anymore. when selecting drawing on the object and framing the head misses the object badly.
