I did another relief engraving. My results are getting more consistently acceptable.
Wil this one ( 80W CO2 laser ) I did,
10% to 65%
enhanced radius 4
Enhancement amount 100
14% to 35%
I twiddle some adjustments based on the shading and detail I see.
My second pass I try to dial in to bring out more of the fine surface detail.
This was in a piece of Walnut ( I think )
