When you say,
Can you please elaborate. LightBurn supports many different laser types so it is not practical for us to provide settings for each material type for each system we support. Running test files to determine the best settings for your laser is the best approach. Once you have dialed in the settings that work best, you can save them to the ‘Materials Library’ to easily apply to a future job.
Below is an example of a testing grid used for this purpose. You will need to adjust the setting within this file for your system.
This test file uses the ‘Power Scale’ feature and this describes how to use it.
Additionally, Boss Laser has a list of starting points for settings on their site, with different values for different wattage machines: https://www.bosslaser.com/laser-settings
It won’t be perfect, but it should get you going.
