I have been using the wizard for external threading and everything works great.  Now I am trying to learn how to do internal threading and have no luck at all.  Everywhere I look there are jillions of things on external, but the only ones I found in internal are from India and I don't understand  them. Can some one please help me to learn how to program an internal thread?  For example a 10-32.Thanks

Hi Piserchio
When I do internal threading using the wizard in Mach 3 all you do
is swap the x axis diameters in the wizard.
I would post a program but my dedicated computer (a 2003 model) stopped working today.

Yes I did that but I found my problem I had I29  and I think it should be I-29 for internel,  it seems to work.
