I tried going through the wizard in Mach 3 lathe, and could not find an option for multiple leads.
What is the best/easiest way to program 2,3, or 4 lead threads?
Can I use the wizard and give it a different starting Z? If I'm doing a 2 lead thread that gauges at 36 TPI, but is cut with 18 TPI, would I start 1 lead at Z0, and the next at Z .0277 for example, and just cut/paste the parts of the program I need together?
There is also a G-code that will make 1 threading cut, but seems really tedious, especially with 3-4 lead threads. I forget the exact G-code, but is that my only option for multi-lead threads?
Any ideas?

On a lathe, use a 36 tpi chaser and cut at 18 tpi ?

When I do multi start threads I use the offset Z method.

I'm not real experienced with chasers, but I don't see how their use would give me multiple leads.
Thanks Graham, I'll use that.
