Hi Ken,
Regarding the threading: I do not specifically mention it, but if you go to the "electronics" page you will see the index board, with some comments. The only purpose of this board is to do IPR feed, which is used by G32/76/96 threading moves. Also to show you the RPM and CSS, which is secondary.
>What is the need for the "Electrically Insulated QCT" ?
I am not sure to what are you referring. It is very simple, and I am not sure what I can add beyond what is on the QCT page. One thing I did not mention is that I added a buffer gate to the input with a 4.7K pull-up resistor. When grounded, the gate signals to the PROBE Mach input. It also turns on a LED on the pendant, as well as activating a small beeper inside the pendant. I placed a post probe connector on the back of my pendant to make it handy to plug in other things, such as the mill Z plate, and my modified edge finder.
Regards,
