Okay, make note - i didn’t do this, @cynd11 did…I just posted it for her here. (For some reason that I can’t remember.)

Again, the bevel doesn’t photograph well but it looks great in real life.
The settings I used for this one:
Four passes of engrave at Speed 1000, Power 100, Map Grays To Power from 1 (not the default 10), focus height 0.05"
Followed by a score of the inner oval at Speed 250, Power 80, focus height 0.01" (one pass).
Then cut the rectangle with Speed 250, Power 100, focus height 0.05", one pass.
