Basically switch BLACK and RED. Black logically makes sense to be a cut so that's what I did (cut on the solid black line)
RED instead should be cut
BLUE should be engrave
Use RED lines to indicate cutting.
Use BLUE lines to indicate vector engraving.
Use BLACK and other colors to indicate raster engraving. (Raster Engraving is not supported for DXF files.)
