I’m trying to create a test grid to test multiple combinations of power and speed. My grid is 5x6 consisting of 30 7mm squares to be filled where each square is assigned to a layer with a unique combination of power and speed. Those 30 squares plus one more for text to label the columns and grids results in one more layer than lightburn seems to allow. At least, I couldn’t find a way to add more layers. I decided to look at a different test grid that had more than 30 locations to see how they did it. I chose a grid used for the Norton White Tile method, but when I opened it, I was surprised to discover that while there was a unique layer for each row, all columns in the row were assigned to the same layer and therefore had the same settings, defeating the purpose of the grid. Obviously, that’s not how the grid was intended to be used, so it must be getting altered somehow when I open it. What am I missing here?
I’d suggest assigning layers based on speed. Then using Power Scale in Shape properties to adjust for different levels of power for the various squares.

As PY said. I’ve done custom 20x20 grids this way. I like them better than the built in tests. Takes a bit to build/edit them, but they’re far more flexible and once you get a couple saved, they can more easily be adapted to suit.
Thankyou PY, that was exactly what I needed. Now I also understand how the other test grids that I downloaded were created and why it initially looked like all of the squares in each row had the same settings.
Thankyou Chris, PY’s recommendation was exactly what I needed to know. I agree that building test grids this way is preferable to using the built-in ones.
