RE: [CAD_CAM_EDM_DRO] USB and ncPOD system

Steve:

Mach3 works great for threading with a single pulse per rev.

Tony, meet EMC2. EMC2, meet Tony. :)

If you'd like a setup that does lathe threading, lathe tool shape
compensation, and actually uses feedback to the motion controller, I
strongly suggest that you try EMC2. Threading requires an encoder with
index - a single index pulse is probably not enough, especially if you
want high quality threads.

Lathe-specific information here:
<http://www.linuxcnc.org/content/view/28/13/lang,en/>, but not
specifically threading.
Some videos here: <http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Videos>,
including some with threading.
(specifically, this one is nice:
