what's the 'resolution of thread' means?

Never tried or used the macro. Based on my poor programming skills, my"guess" is as follows: ::)
The threads as straight line segments NOT arcs, so the resolution is how closely the length of many straight line paths  would be fitting inside / outside of 360 degrees of a diameter.

Setvar(18, question("Resolution of thread"))
Code"#10=[360 / #18]"  
Code"#109=#10"

I am sure Rich will be able to answer that question.

Thanks Rich,
actually I am not trying to cut thread, I want to cut a cone hole of 1.75" large side at high of 0.5" at angle 2.
I can't find any way in Mach3 to do it.
would you please lead me some new ideas?
Best
Adam

You will need A CAD/CAM program to generate the code. Cambam, Fusion 360, there are others.
Enjoy the learning curve.

Thank you very much Rich, I don't have a CAM yet, I'll try. Just wonder if any body can help?

IF you set teh resolution close enough you can machine a taper hole or a cone. Just bare in mine that it cannot remove teh excess material and you have to account for that in cutting the feature
