Before you start

Installation instructions for the LaserSecrets library are included in your purchase package — follow the included video to get the library installed before continuing with this guide.

Open the Material Library and load your LaserSecrets file

Click the Material Library tab at the bottom of LightBurn alongside the Laser tab. Use the Select Library dropdown at the top of the panel to load your LaserSecrets .clb file. Once loaded, expand Stainless Steel Colors → Color to see the full list of colour recipes.

Select your cut layer, then click a colour

Click the layer you want to assign in the Cuts / Layers panel — it must be selected before Assign will work. Then click the colour recipe you want in the library list to highlight it.
