Hi Marty,
Yes that is correct KMotion has built in Amps. KFlop+SnapAmp(s) is recommended as that is our newer, faster, modular, higher voltage, and higher power solution.
We don't currently support threading on lathes. We are working on it now and hope to have something in several months.
The tool changer and MPG should be possible. You would need to write a C program to control your Tool Changer.
Thanks
