I was trying to cut a new air intake vent cover with my new GF. I was having trouble in Inkscape with getting the screw holes placed exactly where they need to be when I thought of using the camera trace function. I thought the trace would give me an exact sizing of the object, but when cut, the image was larger by an inch length and width. Additionally, the exterior cut only offered me the option of manual cut even though I was using proofgrade material. The exterior cut didn’t go all the way through even with a second pass.
I had cleaned the camera just prior to this cut.
