Hope someone can help. I have a Bridgeport Series 2 Interact 4 that has the heidenhain 155b controller. I've switched the parameters to use ISO external input and I'm trying to load a g-code program from the BobCad to the Heidenhain controller. I get it loaded but when starting the program I get a "program start-undefined" error message. BobCad had me download the ISO1150 processor, but my Heidenhain book states that it uses the standard ISO 6983 format. I've tried inserting a CR LF or a CR FF before the % sign as per the instructions in the Heidenhain book, but then can't even transfer the program from the bobCad to the machine. anyone had this problem and knows the fix.
