Laser Test Grid Generator

Generate custom speed and power test grids for laser cutting & engraving, with a LightBurn file that has the settings built in.

Mode

Engrave fills each swatch; Cut draws an outline so you can check through-cut and kerf. Switching mode rescales speed by 10× (cutting runs slower).

Card

Size and finishing of the test card.

Power range (columns)

Percent of laser power across the card.

6 × 4 = 24 swatches. LightBurn gives each swatch its own layer, so the grid can have at most 28 (e.g. 7×4, 6×4 or 5×5).

Speed range (rows)

Max 12 values per axis.

6 × 4 = 24 swatches. LightBurn gives each swatch its own layer, so the grid can have at most 28 (e.g. 7×4, 6×4 or 5×5).

Swatch shape

Colours / layers

Indexed: every swatch gets its own LightBurn layer, so speed and power can be set per swatch. Up to 28 swatches (e.g. 7×4, 6×4 or 5×5). Monochrome: any size, one layer.

Choose the origin your laser is set to in LightBurn (Edit → Device Settings → Origin). If it doesn't match, the design opens flipped.

The LightBurn file includes the labels and logo and sets each swatch's speed and power on its own layer, ready to run. It needs the LightBurn Indexed colour scheme. The card outline keeps LightBurn's default cut settings, so set the outline cut for your material.

How to run this test matrix in LightBurn & xTool Creative Space
  1. Download the SVG and import it (LightBurn: File → Import; xTool Creative Space: Import).
  2. Check the size reads as the card dimensions in mm. The red outline and hole are your cut layer; black text is a score/engrave layer.
  3. With the indexed colour scheme each swatch lands on its own layer. Give each layer its speed and power from the labels: columns are power %, rows are speed.
  4. Run engrave swatches as fill and cut swatches as line. Cut the red outline last.
  5. Write the winning settings on the card with a marker and keep it as your material library.

Power and speed values depend on your machine, lens and material. Always test on scrap.
