I did the etching in the picture. (It was my first time etching PCBs.) The script I used is https://github.com/Formlabs/OpenFL/blob/master/examples/image_to_laser_moves.py which converts an image to a .flp file. That can be sent to the printer and run. If you are going to play with it I recommend getting a pack of blue photosensitive paper that develops in water as they are inexpensive and develop instantly. Let me know if you have any issues. We are trying to expand the documentation and examples to cover what people want to use it for.
