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.

• 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.

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.

• 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.

Once you’re comfortable with adjusting power, speed, and DPI, apply your knowledge in real-world scenarios. Visit our LightBurn Projects – Practical Use Cases to explore applications of these settings on diverse materials.
