I'm thinking actually cutting balsa wood at 3-4mm max. I'm not sure if that's realistic or not, but that's okay because if not I can just add a step to my process and switch out to a rotary tool to do do any heavier cutting. Thanks for the response RedCowboy, I see what you mean, so especially...

Haha, I can appreciate that for sure, plus I don't mind researching it. With the laser setup you reccommended, do you think I'd be able to cut through thin balsa wood and similar with my home made cnc machine?

I see, I'm so glad I came across this forum, because I had no idea how much I didn't know. I'm looking at the link you sent earlier FUBeaches, and I was wondering what the difference is between the three element and the g2 lenses are? I didn't even know that you couldn't use the acrylic lenses...

If I'm looking for the ability to do this burning or cutting, is there a color I should choose over the 405nm for cost to power? To be fully honest I went with a bluray diode because I thought it was decently powerful, but I am willing to change wavelength for more power per dollar.

These were not both hooked up at the same time, it was a small breadboard 5v power supply feeding 5v into the driver, and when that wasn't bright enough I disconnected and attached the 9v battery. I'll post a picture as soon as possible.

The power supply and battery were both feeding into the driver circuit, Would that still possibly be a problem? This is my first build, so I'm sure that scrapping parts is part of the growing pains. Is it reasonable to build something that will be able to burn or cut very thin wood for under...

This is my first laser build I'm currently working on, and everything seems to work, my only issue is that the laser is very dim, and DEFINITELY not burning. I'm trying to build my own laser to use with a DIY CNC machine project I've had in the works. My goal is to make this capable of burning...
