@Chevrc - Is there a particular aspect of your laser engraving that you want to improve? Could you post a picture of your piece along with the source image?
If you want to test the capabilities of your laser more, then I’d suggest burning my test image from above: https://forum.lightburnsoftware.com/uploads/default/original/2X/5/5c858ec5f774402e478c83eba6dc9eb277adca00.png . If you use Min Power = 0% and Max Power = 100%, then you’ll see the largest possible range that your laser can produce (for a given speed and line interval). If your laser doesn’t fire below X%, then you would see that a portion of a row, or perhaps a few rows of the test pattern are completely untouched. You could approximate X = (how many rows + fraction of a row are untouched) / 16. Similarly, you could approximate your preferred max power by seeing how many rows out of the 16 you have to come in from the darkest/deepest to reach the one that you like. Note that the gamma setting (in shape properties) also impacts the output (i.e. if the test pattern slopes linearly, concave, or convex).
