It’s Passover, and you know what that means? Not just fun name plates (see It’s Plague time) but also answering the question "well what food will Feldman shove into his Glowforge now?
So for those interested in lasering their Matza, just to warn you like the tortillas it is nasty after (not sure why laser burned carbs smell/taste so much worse than over burned? @dan? ). Anyway I went with the Maple veneer settings as a baseline (seems like it is about the same thickness and color, which worked well, so that was 300/17 at 270dpi since this piece of matzo was so warped as to make high-res meaningless (plus I guessed it would increase the chance of a burn through). And when I saw warped it technically exceeded .4" in height at the apogee of the arc it only touched the honeycomb at the very edges. As usual the Glowforge’s ability to deal with a badly warped surface did wonders here. For those not of jewish heritage, if you’ve never closely examined matzo it is somewhat unique in that it is 2 outer shells with air in between, except at the perforations which are made similar to raviolis are prepared with. Not sure why it puffs up to form a hollow cavity inside but it makes the top shell very easy to blow through with a laser. And with the air assist you blow the shell apart after it over cuts so gentle is the technique here.
