LightBurn Laser Settings – How to Adjust Power, Speed & DPI
Mastering power, speed, and DPI settings in LightBurn is key to achieving precise, high-quality engraving and cutting results. This guide breaks down these critical parameters, helping you fine-tune your laser projects with confidence.
Understanding Power, Speed & DPI
- Power: Defines the laser's output intensity, typically as a percentage. Higher power cuts deeper but may burn sensitive materials.
- Speed: Controls how fast the laser head moves. Slower speeds allow for deeper cuts, while faster speeds are better for surface engraving.
- DPI (Lines per Inch): Affects engraving resolution. Higher DPI gives finer detail but increases processing time.
Optimizing Settings for Different Materials
Each material reacts differently to laser processing. Here are general guidelines:
- Wood: Medium power, moderate speed, DPI between 250-300 for engraving.
- Acrylic: High power, slow speed, lower DPI for cutting clean edges.
- Leather: Lower power, moderate speed to prevent burning.
Always perform a power scale test before starting production runs to find optimal settings.
Using LightBurn's Tools for Fine Tuning
- Preview Function: Simulate your job to estimate time and visualize the outcome.
- Library Profiles: Save tested settings for each material to streamline workflow.
- Layer Controls: Adjust power and speed per layer for complex projects.
