I've done a few photos on the fiber, but never realized until these that the thing is also engraving the bounding box--
My BIL who works for me has this tattooed on his arm (I fixed the bad spots ;) ) and he wants to engrave it on the blade of a knife he just bought.
However, as you can see, around the photo itself, the fiber 'polished' the stainless. Second pic is a couple of mishmash tests, one was done at much lower power, and one I made into a transparent gif photo and imported it, didn't matter, both of these tests also polished the SS...

The problem is the knife blade has a 'tumbled' finish, and if the laser polishes the non engraved areas, then it's possible the 2 sides won't match. I guess we could simply polish side 2, but that could be a can of worms...
FWIW, it's not a cheap knife...
I'm assuming the laser scans the bounding box by default and etches the 'nothing' at zero power, of which there is no such thing on a fiber, or at least mine, even zero power fires at 1/2%...
So, this post is partly a warning to others, and partly a "does anyone know a way around this?" query... Like, maybe coating the blade with oil or something to prevent the low power beam from marking the metal...
