OK, got some good news! I called Probotix and Jeremy helped me get going (in theory!). The doctor says I have bronchitus or maybe pneumonia (waiting on the xrays) so I can't do anything outside in the heat. I spent about 15 minutes on the phone and he should have me going. I've learned to ask people for help over the years, and in doing so I learned I made a simple but funny mistake!

The front of my control box there is a 110v plug and I plugged the walwart from the relay into the plug. It turns out that is why the first two relays came pre-wired. The plug is for a spindle so the relay can turn it on. I plugged the walwart into my power strip and the green LED's lit up! I did have a couple of things wrong in MACH3. After I plugged up the relay the right way he took me to the diagnostic screen and had me click the spindle control tabs and only the mist relay would turn on and off.

We went back to ports and pins I had the enable 1,2,3 boxes enabled (green checks). I should have had the outputs 1,2,3 boxes enabled (green checked). We cleared that up and now all three relays are clicking and in theory the plasma cutter should turn off and on.

I had to get out of this Mississippi heat. If I feel better tomorrow I may try to cut some hinges for my smoker that I desperately need to finish.

On a side note I asked about the LED's because of the advice from the earlier post, and that help get things going in the right direction. I felt that it was something small. I had to laugh at myself for using the spindle plug for the relay power!
