I have a design that consists of a 5" circle of plexiglass, with an inset circle, 1mm width, that I want to engrave to make space for a small gasket. I created a circle, changed it’s color, make sure it was not filled. when I upload it to the flowforge, it shows up as a cut. when I change it to an engrave, it recolors the interior of the circle as though it plans to engrave the fill.
Can someone suggest what I might be doing wrong in inkscape?
