On LightBurn-machine setting pages you will find a Test Grid Generator in the sidebar. Give it a center power and speed (it prefills from the setting) and it builds a ready-to-run .lbrn2 grid where each square is a different power/speed combination.
Run the grid on scrap, pick the square that looks best, and you have dialed-in numbers in one pass instead of many trial cuts.
