I am retrofitting a home built router and using Signlab to generate my cut files. The router has 3 stepper motors and I am using Mach 3 to run the router. I have successfully output a polylineDXF file from Signlab and cut it on the router. The one feature that I can't figure out how to accomplish is the S-Sweep to cut out the background and leave the border and the letters for a sign. Does anyone have any experience on what type of command and what type of output file that works best for this operation?

There are others in here that should be able to help... I cut parts for machines so I am no help
