A40640 marking on metal

Bought the laser by Neje consult to make a logo on pen clips.
Success on knives that made from stainless steel but not on clips that have different plantings (chrome, gold, silver…).
Will appreciate you’re help with that.

Hi MishaManusov,
welcome to the forum.
You can “engrave” high-quality stainless steel and remove the paint from painted metals, or engrave the anodization down on anodized aluminum.
Not much more is possible with diode lasers.
For engraving on various metals, a fiber laser is a good choice.
