Not a newbie to CNC. I have been running a Victor TNS-3 w\ Fanuc 10T and a HAAS HL-2 for many years. I was trained by a former employee before he left for another job. He trained me in G-code and everything, which has been enough to get me by.
But I always thought there was more I could learn to better myself in the industry. Like the Canned Cycles I've read about on here. Now I did try and got a G83 Peck drill cycle to work, which saves quite a few lines in the program. But like I said there seems to be so much more to learn. I have looked into the G71 or G72 canned cycles, the roughing one. Now what I have seen on here some of the letters I am not familiar with. Like U, W, J and some others that escape right now.
So any input would be great.
