... here some samples of "micro-machining" - did tests with varying hatch-densities and repeated engraving in brass and a multi-layer ceramic part.

First the tests in brass - with 30microns hatch-spacing and 10x ablating it will "engrave" 0,3mm deep:

... in ceramic it's a bit more effective - same parameters and 10x engraving will remove 0,6mm:

... not precise/fine enough to make own coins, but good for some laser-"engraving" and "drilling" ;)
