One totally different thought, is to place a "spoil board" and fix it to the machine. If your looking to nest wood, you can place a full sheet down, than nail in place using fiberglass nails. Than program your file to make a 1/8" score trace of the parts on the full sheet, this is so you can see where you need to shoot additional nails to hold the part down, than once that is done you can run the full program.
The other way is to use double sided carpet tape to tape the sheet to a spoil board. I done done and have worked out very well.
