I printed some decals that I want to contour cut.  My Graphtec is reading all the registration marks, then starting to cut, but the cut is off.  I stopped the machine, and pressed the cancel job button.  When it "Canceled" it starting cutting a diagonal line from the place I had stopped it all the way through my decals to til it reached the center of my sheet. Then it started cutting out decal shapes again.  I "canceled" again, and it did the same thing.  Dragged the knife diagonally across all my decals until it reached the top right registration mark!  I am beyond frustrated that it did this because now I have to re-print all my decals.  This is not the first time it has done this when I have canceled a job.  Does anyone know what causes this and how I can prevent it from continuing?
