Lock in your half nuts anywhere and run the carriage a bit to take out the backlash. Shut off the spindle motor and then take a sharpie and make a line on the thread dial opposite the index mark on the housing. Just keep using that same line on the half nuts. If you get double tracking there a mechanical problem in you feed or thread dial.
