Why use a test grid
Learn your material before committing a design
Wood, slate, acrylic and coated materials react differently. A small labelled test grid lets you compare a limited power and speed range on the actual offcut, instead of guessing on the finished product.
Practical guide
Find a useful range on a real offcut
- Use the same material, finish and thickness as the final item whenever possible.
- Start with a small conservative power and speed range rather than testing the full machine range.
- Choose rows and columns that leave enough room for labels and set a physical cell size you can inspect easily.
- Download the SVG, confirm its dimensions in LightBurn, LaserGRBL or your editor, then assign the operation there.
- Run the grid only after checking focus, ventilation, material safety and your machine’s normal safety procedure.
Questions and answers
Before you run a test
Does this choose the best power and speed for me?
No. The grid is an experiment planner, not a preset database. Laser power, optics, focus, air assist and material batches differ, so you must judge the result on your own machine and material.
Can I make a 4 × 5 or 10 × 10 grid?
Yes. Choose between 2 and 10 rows and columns. Larger grids provide more comparisons but need more material and leave less room for each label.
Does the SVG control my laser?
No. It contains only labelled vector rectangles. Import it into your laser software and choose the layer operation, focus, safety checks and final machine settings there.
