So fabmaster nests the files and exports an nc file which consists of G Code. You can set the quantity of parts before you nest it, it then creates however many parts you requested. The code it stops on is "G4 P.1" that's the whole line. Yes there's a period in it, not sure why, but there's the same code in the first part which works. It only asks for an E Stop on parts 2 through 5.
