I did go to ports and pins and unchecked port 1. I measured pin 6 and ground to pin 25. I got a steady 0.5 MV

is port one still disabled?
I believe it would prevent mach from doing anything on that port.

As I see it and maybe I am wrong but Mach DRO is running. It just isn't turning the machine

Ok sorry just read again after woodspinner asked that question. You do not want Port 1 disabled, if you do that then you will not get pulses from it. What I said was change the active state of the E-Stop in ports and pins so that when you pull the cable from the port you are still able to Reset Mach. That way when you command a move the port will still be getting the pulses.

Okay, I went to ports and pins, Pin set up and checked the box to enable port 1. Moved to Input signals, Found E stop  box and changed it, Clicked apply and okay. Rechecked and it had changed back. repeated steps half a doz times with the same result

I did take a reading anyway but no change except in G0 the reading is 0.6 MV instead of 0.4 of g1

What did you change in E-Stop? It is the active state only that you need to change, did you try and disable it?
You need to be able to take Mach out of Reset before you can test.
0.4 or 0.6 mV is next to nothing and basically means nothing is coming out of the port, if Mach is in Reset (Reset flashing) then that is to be expected. If Mach is out of Reset and you are jogging then something is wrong, either you are trying to read the wrong pins or possiobly you have the meter set to something other than DC mV scale.

The only place I see a E-stop mentioned is in ports and pins, Input signals, scroll down to a box titled E-Stop and I unchecked this box turning it to red. It doesn't stay red and I don't see any other place to do any thing with E=Stop

In the same line as that you have port number and pin number then active low, put a tick in that box so that when you pull the cable out Mach will still think the E-Stop is ok and you will be able to reset.

After some thought it is possible I am reading the wrong pins. I am off tomorrow and can work with this then. If the diagram that I have used of the PP end is female then I need the mirror image of what I am testing. I will reset E-Stop and start over. . Thanks for your help and patience
