3000mw blue laser engraving machine upgrade

Opinions are the Only way to get Info without Spending A Lot of $$$$$$$

How is it for engraving glass or acrylic and cutting stuff? lol
I plan on engraving drink glasses and other Ideas lol and cutting
not too thick wood.

According to Banggood… sculpfun S9

Laser effect power:Cutting effect similar to 90W CO2 laser
Laser output power: 5.5-6W (light energy)

Is it really that comparable?

The Only thing I Know about CO2 lasers is that they use Carbon Dioxide lmao
And the ones I’ve seen pics of you can’t see the beam

For $60 cdn more then the sculpfun S9 module.

NEJE A40640 Laser Engraver Cutter Module Kits

Optical power output 15W (15000mW)

Might be worth the extra power???
