I used blue for cutting and black for etching, I used the circle shape in inkscape to create the etching.
I etched this into 3mm acrylic.
Reading the forums, it seemed that the maximum etch depth was .5 mm on acrylic, which was pretty close to what i wanted.
I've checked the svg/inkscape file and I don't see blue borders on the shape. Am I trying to do something that cannot be done?
I'd like to prevent this in future designs.
