How to engrave a picture
On the way from the Lodge I told Finn "We don't want to go saying stupid things, like 'an Octopus in a Tuxedo."
"What's wrong with an Octopus in a Tuxedo?" he asked, quite reasonably.
I waited for a safe place to pull over, and
Asked ChatGPT "Please generate a picture of an octopus wearing a tuxedo." "
How to I engrave this?
-
magic wand select the almost-white and fill it with true white. (convert transparent to white)
-
remove the arc of black dots, I don't know what that might have been, but I don't like it.
-
Edited out details I didn't like. Saved it in gimp XCF
-
Convert to Grayscale Image->Mode->Grayscale
-
And then convert that back to RGB Image->Mode->RGB
-
Save it as a JPG
Cast acrylic is better for engraving than extruded. I used some 4mm smoke colored cast acrylic from my old days in the Tap Plastics off cut bin.
Engrave: speed 300 power 40 Cut: speed 20 power 85, 3 times.
The paper barely had ghost marks. I think going faster and doing more passes is helpful.
