So I finally upgraded my generic laser engraver from its stock "2.5W" which turned out to be 1W. I replaced the diode with an nubm47 and am successfully
etching into aluminum with the aid of black marker @5.5W.
I would love to be able to etch PCB's by burning off the copper clad and avoid toner transfer and acid baths, or router dust. So my question is how
much power do I need at minimum to get into the area of diy laser etched pcbs?
I know that a co2 laser is ideal for such a project, but ive got time and diodes!
Im thinking 4x nubmo8's paralleled and some expansion optics to reduce spot size. Any thoughts?
