Thanks everyone. Alex I use spray glue to adhere the photo. I don't get any charing or evidence that the laser leaves behind. Using 3mm plywood makes them so they should last a long time, but I think the next few will be using poster board so they will be like the puzzles you can purchase. I didn't like anything I found on line, so I created the pattern in Illustrator. I have a SVG file for 9, 15, 36, or 99 pieces I have them made and if anyone wants files let me know.
They finished up great without the laser marks... I get a lot of laser marks... maybe it's just because of the MDF. I use low adhesive stick on laser masking tape, however, it's a pain removing it after the cut.
Poster board sounds interesting.
I wouldn't mind a copy of your SVG files, if only to expand my jigsaw arsenal.
FAIW, if you are now aware of it, this link is a great site to generate customised jigsaw aptterns... the only down side is that the pattern is the same though the layout is seed generated. The HEX creates an interesting jigsaw. The pieces are subtly different and when the same shape, the picture would be different. Unfortunately my sample is not G rated for posting here.
If your first cut is too short... Take the second cut from the longer end... LBD
