I have the drawings for this puzzle in Inkscape so I tried it on the laser in cardboard.
I sent it to PDF, opened the PDF, went to the printer driver and selected Vector, 1000dpi, Max Speed, 15 percent power, 5000 frequency and I changed the vector sort to inside to outside. Presto, vector cutting!
I had to do a second pass as this was just enough to get through the cardboard.
The only problem I had was for parts that are larger than 8.5×11. I found that it either scaled or cropped. I hope we’ll discover the answer to that tomorrow at ModLab.
