This will be impossible to answer without having the same setup and materials you have. Your best option is to build a series of sample patterns with varying speed and power settings to test the exact configuration and conditions you’re presented with.
LightBurn provides helpful tools to create such test files. Using the ‘Array’ tool, you can quickly build a grid of test patterns, patterns you may have already added to your ‘Art Library’. You can quickly apply presets from your stored ‘Materials Library’, copy and paste entire layer settings and more. With a better understanding of what you are wanting to accomplish, what you have tried and what your results have been, we can offer some suggested workflows.
