Genmitsu Z5-1 Fiber Laser Engraver | POV | Would you buy it?

Wattage? Sorry I heard that was important. Can’t seem to find that on any vide I’ve seen.
I want something for my business. No images
Just part numbers. Will be marking exclusively on metals Al, Ti, bronze ,stainless

Do you use special settings for engraving metal or you leave everything on default?

I’m stuck! I can’t get it to mark from an image (jpg or png). Insee the laser tracing the image, but no mark. I thought it might be the material, but when I draw something from within the software, it marks very clearly. I can’t find tutorials on this anywhere… any chance you can point me in the right direction on this?

Can this engrave 14k gold?
