Very cool. What's the ComMarker costs and specs needed to etch into steel? Presume it's pretty powerful. Thought about how you can do descriptors too? Is it this one? https://store.commarker.com/products/b4-fiber-laser-engraver

Some questions: - Can it do descriptors? - What wattage engraver is needed to engrave steel? - Does it print the words on steel as well as the QR?
