In my #LaserEngraving adventures, I finally cracked the code to get some proper depth on 3mm acrylic engravings without getting a warped potato chip.

It comes down to the following:

* Low-energy fast passes (I'm doing 9000mm/min at 30%)
* Cross-hatch the engraving
* Lots of passes (picture is six)
* The _gentlest_ bit of air assist

Really happy with that - decent depth and no warping!

A piece of engraved black acrylic shaped like a section of floor. It has some geometric lines and circles engraved on it, as well as some cracks and other chips and damage. There is decent depth to the engraving.
