In do have some experience with X Y Z programing on a milling machine but i know nothing about C axis programming. Centroid has a video of the type of work i need to do and a sample program. I was hoping someone could help me decipher the sample program so I can learn how to deal with this. I would guess that all the programming would start at zero degrees. And C- would rotate the spindle clockwise and C+ would rotate the spindle counterclockwise. But if you look at the program all C axis moves are C-????

; This set up was the a gang style lathe.
; Tool 1 is a 1/4" end mill in a Live tool holder.
; Live tooling has the 1/4" end held horizontal to the X axis plane.
