We found this inkscape extension to generate puzzle vector patterns, so I decided to give a try.http://tuts.ahninniah.graphics/how-to-m ... d-inkscape
We created a 10" X 10" puzzle in inkscape and saved it to a DXF format. We then imported the file into KeyCreator to generate the gcode for cutting it with our 6W laser diode.
We first TTL laser engraved (pulsed on/off) a B&W image on 1/8" Birch Ply the same size as the puzzle pattern we created, then cut through the Birch Ply afterwards. It has a total of 144 pieces.
