It would be helpful to have a “scan from tablet” mode that:
Turns off the lights in the glowforge, using the [suggest maximum brightness?] tablet as the light source. This both looks sharper and eliminates glare.
Adjusts the focus of the camera to be ~0.25-~0.3 inches to improve the focus.
Nothing going to happen on this front. The lid camera is a fixed focus lens.
Edit: as well as fixed aperture. This wide of a lens, at the narrow depth, is going to be within the lens plane of focus. If your camera is blurry on this, it’s just as blurry on any other image. Might try cleaning it.
