That last file is a bit different.
The first hole is at 0,0 then the rest are at .97, 2-4-6-8-10-12 making the first two 2.223 apart and the resr 2" apart. And you're drilling the first hole twice.
I don't understand what is happening with yours. It runs as programmed here.
Maybe someone else can see a problem.
