Help with speed and power

I been try several test to have the right power and speed test in my Atomstack X20 pro 130W, and every time it burns my material, is any of you have a start point I can use to help me, Thank you, have a nice day.
Sincerely Jose

In Lightburn you need to select laser tools from the menu bar at the top, then select material test. You will then be able to generate a power and speed figure that will let you assess the settings you have and would like to use.

And if you cut a bunch of holes in the material, set the max power to about half and do another.
