Ok, trial by fire is done, mostly… Still some tuning, I think.
First result wasn’t so good. See the top burn in the image below. Remembered that there was a long thread about the firmware changes need to make the lasers work properly with Marlin (https://forum.v1e.com/t/laser-engraving-not-really-getting-great-results/). Went in there, applied the source code change, and burned the text in the bottom portion of the image below. So yay! Thanks to all you guys that have come before me! 
Still some tuning work with LightBurn, I think…
