Threading question

[Racer X]

I am new to lathe programming and am limping along trying to get a part up and running. I need to do a left handed 14mm x 1 thread. How do I get X3 to give me the option of spindle rotation.

 

Also, what does "Negative X" mean on the thread shape parameters page?

 

Thanks in advance

Actually you don´t have an "option button" or something like that for the spindle rotation.

The spindle rotation depends only from your tool.

Check your tool, you will see in the "setup tool" page the spindle rotation. Oay atention when you change the spindle rotation changes also the position. Check this with the "draw tool" button.

 

I don´t know what is the "Negative X" never use it.
