Yea, you’re going to need a lot more than 2.8 watts. You’re going to be looking at 30 watt minimum, and at that, it’ll be going stupid slow. Also most solid state lasers your going to get off ebay or amazon are the wrong wavelength to do anything to metal. You’re going to need a co2 or nd:yag to cut/engrave metal reliably.
