I used the emboss function of the Ultra rather than engrave because currently there is no crosshatch available for engraving. The emboss allows both a change in angle of scan as well as a z axis descend, useful for a bit better depth.

I used settings for this one that only incise a shallow set of lines and you could easily alter the number of layers to go further. This is also a very useful technique for applying layouts for subsequent hand engraving.
