LightBurn Material Library: save, load and assign
LightBurn's Material Library stores settings you can reuse. Save a layer as a preset, or load a .clb file through Manage Library. Assign copies a preset into a layer; Link keeps the layer tied to it. Keep the source document and exact machine context with your own notes.

Save or load a library
Open Window → Library if the panel is hidden. To save a layer, select Create new from layer, then enter its material, thickness and description. Under Manage Library, use Save Library to keep the file, or Load Library to open an existing .clb. These controls come from LightBurn's library reference.
Choose Assign or Link
Assign copies the selected preset into the active layer. Later edits to either stay separate. Link connects the layer to the preset: changes to that library entry flow into the linked layer. LightBurn recommends a separate library for each laser. See the Assign, Link and Multiple Lasers sections.
Check the settings in context
Open the Cut Settings Editor by double-clicking a layer or library entry. The available controls depend on the laser type and layer mode. Speed, power and mode sit near the top; other controls appear below. Read LightBurn's editor reference for the controls your device exposes.
Check both parts of a speed unit: distance and time. LightBurn tells readers to match the source units or convert the value. Its speed documentation also explains that a machine may not reach the entered speed. Our speed unit converter handles the arithmetic.
Keep a source note beside the preset
For your own record, write down the exact machine and module, material composition, thickness or coating, operation, and document URL. Add the date you read it. That is CutChart's suggested note format; it is not a statement that LightBurn requires those fields.
A downloaded file can leave unanswered questions. Which machine did the author use? Does the quoted document describe cutting or engraving? Have its conditions been preserved? Our source process explains how we approach those questions. The available tools show what you can check here today.
CutChart has no verified .clb download available yet. We will publish a file only after checking its source settings and import behavior for its stated device. See the scope of CutChart before treating a page as hardware test evidence.
Common questions
Does CutChart offer a LightBurn library download?
No. This page explains the feature. CutChart has not released a device-specific .clb file with verified settings and a checked import.
Can the speed converter move a preset to another laser?
It converts units only. It does not establish a suitable power, speed or pass count for another machine.
