Here it is:

Not perfect, of course, but considering the quality and cost of the tool I am completely satisfied with this result. This precision should be plenty for the through-hole and larger smd circuits I build. I am overjoyed that I finally have a chemical free way to make pcbs at home.

Thanks to the people who gave me feedback and followed this project. It's not over yet, though. I still need to finalize schematics and clean the code before I post them here, but that will come in the next few days I hope. Also, I need to produce an actual pcb. I'm thinking a small celebratory robot.
