I have a Nardini lathe with a Fanuc 20-TA control and i am trying to cut a left hand thread. I fill out the form for threading Z1=0. then Z2=1.00. I now get an alarm stating Z2 is larger than Z1. and i can't get any farther. I wish to thread from left to right
I hope that some one can help me. Thanks

are you trying to do this through FAPT?
 
Fanuc 21 maybe?


The only thing that comes up under Fanuc 20 is a 20kg robot.
???


As GD said, look up G76.

Fanuc did make a 20. I've only seen them on lower end machines. I'm pretty sure it is not FAPT. Some flavor of CAPS maybe. In any case, a conversational programming system.
