Jpeg, gif or PNG images can be used and they do not require conversion to grayscale (that happens inside with the magic and stuff). I am not quite sure what happens if you feed it grayscale images.

Problem Statement
I got a 2W blue laser and I zip tied it to my 3D printer to cut simple shapes out of paper and cardstock. I attempted to find rasterization programs for image etching but I could not find anything worth using. I decided to write my own program because it seemed somewhat trivial yet also, well, lasers!

TODO
Lots of stuff to do, but it would be nice to have:
- Bidirectional mode
- Skip over (but don't violate overscan distance) large white areas.
- flip images with tic boxes
- generate a power calibration script and greyscale boxes.
- Stationary Dot-matrix mode with variable power pulses instead of traveling lines. Newsprinty-halftony-thingy.
Solidoodle 3 2W Blue Laser Results
Etching paper has proved pointless, as the difference between a mark and a full through burn is incredibly small. However, balsa wood has proven to work extremely well and the results have been most satisfying!
