Trying to impress SWMBO, I used a picture I had taken of her a few years ago and imported it into LazyCam as a jpg. I set the maximum depth of cut to about 90 per cent of the thickness of the Perspex material and using a hand ground 60 degree engraving cutter, let Mach do it's magic. The size is about 60 x 60 x 3 mm. She has it displayed so visitors can see it, so I guess she was quite pleased. The pictures are of the original photo, a backlit one and a sidelit one to show the machineing marks.
