should your FIRST laser be a diode? 

Yes.

How to act when/if material catches fire? (maybe a video idea for future?)

All these bleeps sounds like an episode of COPS. 🤣

Guys bit of a weird question. I have had a gantry style laser for over 2 years (never even used it) with a atom stack R30 V2 head on it. When i use the test buttom at least something happens but its supposed to be full power. And on metal and anodized material it does absolutely nothing. On wood it make a little black mark. Any ideas? You guys are a bunch of clowns and I love it😂

Hey I’m new to lasers i bought a 20watt Atezr diode laser what is a really good set of glasses should i get i need them to fit over prescription glasses

Always nice to see you.
