@mikejoslin510 .....Well, after the 100 watt laser upgrade I can cut Wood at about 16mm thick, Acrylic about 20mm thick (but wouldn't like to pay for it) plastic BUT not any steels or metals.
I can burn a hole through the 0.6mm stainless steel top but not cut any shapes. If I put an Oxygen assist then I could probably cut stainless steels about 1mm thick but very slowly.. Thanks for asking. :-)
So, if you wouldn't mind messaging me, why won't an A/C capacitor bank charged from the wall with a resistor right onto a diode set in a waveguide work?
Yeah, it sounds a lot but I priced JUST a table from ULS.inc through their sales reps in Australia and they wanted $46,000 THEN add $6,400 for the 30 watt laser tube and you can see the path of build-your-own was a no brainer. I am happy!
It took about 3 months to build and another 2-3 months to iron out the bugs with the software and hardware. It was originally servo drive but I had no luck with them so I converted back to stepper drive with little degradation in performance. It won't cut thin sheet, even foil but it eats up paper. About the limit is 2mm cardboard/chipboard. anything thicker and you can sleep for a night and come back when it is just finishing. (kidding). It is really slow with thick stuff.
What can you cut with this?

Great build. Do you have a "Build log" somewhere? And where did you find the lens assembly?

I'd also like to see a build log, so much stuff to learn. Well done!

@valordk I cant make an url work in the comments. Try cnczone and search for "Backyard Laser "

impressive! I bet you keep your fingers away from the beam between the mirrors!

Actually, I have no idea as I am not a technician. Wish I was though. Are you talking about Nd:YAG lasers or the CO2 lasers?
I really don't think I can help you out here, sorry.

Mate, not bad at all in fact excellent and i'm very happy for you as well, but for $6,000...ummm...!
I guess trial and error means money!

Bloody everything expensive here, i suppose you're very productive now!
Roughly, how long did it take you to build? When i have the $6000+ and sometime, i'll follow your footsteps!
I think its very nice to have laser for cut paper (various sizes) or thin sheet metal.
Still very exciting watching it works and do things!
Cheers,
