Awesome, thank you! I could have Googled this, but it is always awesome to get information from someone who can give a better summary.

Since you are closer to the laser etching/cutting aspects than I am (I have a traditional hobby CNC machine and do a ton of 3D printing), I am curious if hight mapping has been integrated into laser etching yet. The reason I ask, is that when I cut fine pitch PCBs, I need to be at very specific depths of cut, usually within 0.1mm or so when precision is required.

Working with small curved surfaces could be problematic for maintaining the correct laser focal point? Maybe? Possibly? Even applying a generic hightmap could allow for better etching consistency IF high precision is required. If that doesn't matter, cool.

In the low-end space where I play, and I think well into the mid-range, the engraver/cutter is on a 2d gantry, basically a Core-XY 3D printer with no Z axis. I focus manually with thumbscrews and a shim. 3-axis and even 5-axis lasers exist, but I think most of them are industrial class.
