Laser Engraved Wooden Calibration Test Grid

Information

      This is a LightBurn material test card, commonly used with laser engravers to determine the ideal combination of power and speed settings for a specific material. 

Here's how it works:

Rows (vertical axis) represent different engraving speeds (measured in mm/s).

Columns (horizontal axis) represent different laser power levels (as percentages).

Each square in the grid shows how that specific speed-power combo affects the wood: darker burns, lighter marks, or even no visible change.

Numerical labels along the edges help track which settings produced which result.
