Most LightBurn cameras are manually focused by twisting the lens.
The camera should be focused as well as possible.We generally recommend mounting on the inside of the lid, when opened, like this: The ideal mounting position for the camera is directly above the center of the bed of the laser, with the bed completely in view (similar to the image shown above).If you are installing the camera yourself, there are a few key things here worth noting. If your machine already has a camera installed, you can skip this part. It takes a bit of effort to set up, but it's worth it. LightBurn will correct for this, as well as mounting at odd angles, and will simulate a clean, top-down view of whatever is on the bed of your laser. This image is fairly distorted, because the camera used here has a fish-eye lens.
As such, some software cameras (such as OBS Studio's "Virtual Camera") may not present as a camera at all to LightBurn, or may render incorrectly. LightBurn only supports the use of UVC-compatible cameras.
