Did you check the haascnc website?

I suggest the lathe workbook for you.First you get good, then you get fast. Then grouchiness sets in.

Hopefully this is helpful. I am currently studying cnc programming. I wrote a program for a 1-1/4 11.5 npt and it worked out great. I made some adjustments to suit your 2 11.5 npt So hopefully this is usefull.
