Well I had some time today to connect the 7i76e to the stepper drivers, power supply, and stepper motors. So far all is
working well. I had an easy test G-code to run and aside from some unintended weirdness ( most like from things I don't
completely understand yet ) it performed as expected umm in a good way. I will Shoot some video this weekend.
Stay tuned.

Looks like I will have a lot of video to shoot . I hooked up the spindle VFD and after fighting with some settings
the VFD will now work with the 7i76e board . I also got the spindle encoder electricly connected so I can see the
spindle rpm ( when it's physically connected to the spindle ). Now if I could just get the MPG wheels to work . LOL .

I found the answer to my MPG issue. One I have to have the "machine" homed before the MPG Jog Wheels will move an axis.
the last thing though is in Pncconf. The "External Controls" page I had to change the "Default" setting from 0.0000 to 0.0010
Now it works . Talk about a " cant see the trees through the forest" type scenario.
I later decided to use a selector switch for MPG jog rates Default 0.0000, A=0.0010, and B=0.0001. So now the MPG wheels are
ignored until I select a Jog Rate.
