re: Laser Engraving Metal

Jim, it all depends on which type laser you’re using. Shiney metals don’t work well with diode lasers, especially lower wattage lasers. Near IR lasers are the inexpensive way to get around that. I’m sure happy with it thus far. It was a shear stroke to find the conversion cable readily available. Building one wouldn’t be so hard, but you’d have to understand the pinout. Having it ‘just work’ was sure a nice surprise!
