The Geckoflash code program for the G2002 is called MainFirmware?.bin. This firmware program will make the slab operate in a "dumb" mode whereby it recieves a simple protocol of velocity words and feeds back inofrmation to the Mach2 program. It is incomplete in that it does not support homing or limit siwtches. All movement aspects do function however. This is a beta release and a test version on the path to full support in the G200x to be released later this year.
