Sorry @Jules, I could not resist giving this a shot!
Shall I spoil your fun of discovery? I will say, this is 1/8" PG black acrylic and this was a single pass.
I used a real 100mm macro lens on an actual camera so beware it shows every last gory detail (ie: it looks better to the naked eye, the photos make it look like lava rock LOL!)
So I was playing with tapers a bit too and (at least on wood) the new greyscale engraving seems to work really good without any changes to settings. Did you manual engrave this bevel? If so, what changes did you find worked better. Just curious, ill probably do my own testing tonight.
Yes I was using manual settings, in this particular case mostly to reduce the LPI settings just to make it faster for testing the proof of concept, plus I wanted to do a deeper bevel than the stock engraving settings will allow.
This is awesome work! That last one is so clean and beautiful. I’d love to see a pic of the file you used to create it (unless its a trade secret or something ). I can imagine the greyscale image you used, but my brain just understands things better with pics.
This particular sample was ran in 3 passes following what I learned from the thread in Beyond The Manual - less “heat”+ less speed = better surface finish.
