4mm Beech-wood cutting?

Hi!

I’m trying to cut out some animal forms from a 4mm Beech kitchen spoon with the Opt 6W laser.
The results are real bad. Do anyone have any recommended settings to cut them out?
I’m using Lightburn.

The Form didn’t fall out, i had to broke it out with hand. Tried a lot of settings but can’t find the right one.

Ps: my english isn’t the best, sorry.
