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. Also, depending on your machine's axes the image may or may not need flipped or rotated. At some point I will implement this but for now you should make a small 10mm test and see for yourself.

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!

First tests. Not too bad!!
More testing! More laserz!
