Here is the code I have tried. I am on the back turret of an LH 35N so I am threading from Z-2.0 to Z.250 which should be 2 pitches in front of where I want to start adn 2 pitches past the end of the stub..
G71 X6.396 Z.25 I-.089 B60 D.010 H.100 F.125 M23M32M75
My problem is probably part code but I think more that I don't really understand the start and finish depths that I should be using.
Any help is really appreciated, I really need to run these parts tomorrow!!
