As a note, I use these test files on my XTool D1 Pro 20W. It should also work for other lasers, but if you’re using a laser that is much more (or much less) powerful, then you may want to adjust the settings.

Or, if you’re testing a much different material (I use this primarily for various types of wood), then you may also want to make adjustments.

For example, if you’re trying to find the settings for cutting cardboard, you probably don’t want to use this file as-is, because it could cause a fire. Proceed at your own risk, and be mindful of safety.

With that said, I think this will give a lot of folks a good start-point, so I hope you’ll find it helpful. Happy lasering 🙂
