I was just wondering… is there anything like a fumes detector for laser that would alarm you when you cut a material that should not be lasered? I know the general DON’Ts materials for laser but I’ve had some hard times finding out about the exact composition of some of the not-so-straight-forward ones. If something catches on fire is clearly not ok but there are many materials that are harmeful but there is no way to see it. For example a chrome-tanned leather. It´s been a nightmare for me to find a reliable supplier of veg tanned leather so I just gave up on leather projects (shipping costs of proofgrades are killing me so this is not an option).
I was thinking that some kind of a detector of the most common laser-related fumes would do the trick. You could just forget about all the secret ingredient search, put any material in the laser and if the buzzer doesn’t go off in few seconds you’re good to go. It would make my life so much easier!
