I usually use the 0.060 for earrings and such but have also used the 0.020.
These are saved in the UI as .02 Engrave // Score //cut and also 0.060. Which is nice because when that material is submitted they show up in the UI list.
If nothing else, these should get you into a ballpark area. I have seen some 0.020 acrylic that the engrave seemed very heavy, but I think that is because of different materials//thickness variation than the actual numbers being wrong, and also, because if the thin stuff is not held down well, it tends to bow from the heat…
As always, test on a small chunk before committing to a large design.
