I am a shop teacher just learning the CNC side of machining. I need to write a program to cut 1/2-13 threads for a school project. We do have a spectra light 400 lathe. We can use a cam product to draw and produce the cnc program automatically. It produces a canned cycle and when we put it into the lathe program it will not move in the z direction. The tool will move into the X position and the spindle will turn on. After talking to consultants they think there is something wrong with the lathe. Anyway I would like to try and write the code manually. I have a small understanding of the code and just need some help.
Thanks.
Jack
