Power Settings in Engravemode without function?


I just made several tests with the Engraver with different speeds and power settings. If i try i treshold of 100%, almost everything is black (not in preview). I engraved on some cork pieces. You can see, that the intense of the laser is changing while it tries to make the gray zones. But even if i go back to 10% power, the laser is to strong for cork. Even with very high speeds. So is the power setting functional?


Grayscale printing does work better on other materials.
Its almost impossible to get the cork burn/scorch for 50% for a lighter tone.

Mayby Flux should incorporate functions like this https://www.youtube.com/watch?v=c5GNzBbbMW0
