If you were using the haas simulator, you left your knurled pen behind. It is with me. cheers!
I first interpreted that as a g-code file for a nice knurled pen and was trying to imagine how one would do that with the HAAS.

it is probably possible to do this using a mill thread tool with a tight number of right handed and left handed threads to create a crosshatch.
however, thread milling is very memory intensive. Our old girl might get one thread done before running out of memory.
