Raycus 50w

i have raycus 50w laser and i want to know where i can find file like this to know which parameters are the best for each material

I am engraving metal cards(matte,brush,mirror)and I can’t find best parameters for each material

You can find related videos on YouTube or join a facebook group where someone will share the file.
These engraving parameters are for reference only, the results may vary in depth due to lens, power laser source brand, metal mix, ETC.
