While exploring what I can do with my cnc machine, I found a cool way to make the engraving subject unique. By breaking down a photograph of the subject into a cluster of dots, the carved image did not have to be the usual combinations of lines.
Of course, the time taken to cut the image did increase a lot, but with some patience, the result can turn out to be very nice.
I used a 60-degree cutting tool for cutting the dots on masonite board that was previously sprayed with a layer of white paint.
