Hey Slatye,

I think a camera would have just a way too small resolution.
If the image would cover the build area and nothing else, you would theoretically get HD resolution.
This won't be the case as you also have to analyse the image (the laser point will look a lot larger that it actually is) plus you will have calibration errors (skew camera, ...).

My current problem is that everything I can think of requires precise optics...
