I believe I have solved this.
The MDI is now working the first try every time so far.

Apparently there is some "better" logic between the Pokeys, ESS, and Mach4 that it likes a little better in regards to the E-stop settings.

I changed the Mach4>Control Configuration>Input Signals>E-Stop to Active Low (which is Pokeys pin 18)
and the Pokeys Plugin Configuration>Pokeys Mapping>Pin18>Inv.pin to "X"

They were opposite, which worked, but it seemed to not like it. Oddly enough this also eliminated one of my bootup messages.
It used to go:
-----ESS: Limit Switch triggered on
E-Stop cleared!
E-Stop condition!
E-Stop cleared!


Now it goes
-----ESS: Limit Switch triggered on
E-Stop condition!
E-Stop cleared!


The ESS still flags and acknowledges an E-stop with the red LED, the same as it did before. So, I think all is good now.

Any ideas why I get "E-Stop is in effect!  Clear the E-Stop condition." when I hit the Cycle Start Switch?

I boot up, home the machine, I can jog around, run probing, or whatever, but if I put a command in the MDI and hit cycle start, I get "E-Stop is in effect!  Clear the E-Stop condition.".
I have to hit the E-Stop switch,then pull it back out, enable again, then from there on out the MDI seems to work. It seems to do it only the first time I try to use the Cycle start to issue a command (just doing an M6 T(tool#) to make a tool change).

Using ESS for motion and Pokeys 57E for mechanical input switches. I have a feeling it is a setting somewhere. In the mean time while waiting for some feedback I will dig around. I think I can reproduce it reliably, so that may help.

ESS FPGA Signals>FPGA Input Signals (1)> Estop is not checked in the diagnostic.
FPGA Status>FPGA Status Bits (2)> Estop is not checked in the diagnostic
Pin 18 of my pokeys is lit green (goes low when the E-Stop is hit)
The red LED on the ESS is not indicating it is getting an E-stop

I ordered a set of gage blocks. I can stack them I guess to get them high enough.
I have questions about this though.
"Then you measure the distance from the end of the spindle probe to the end of the spindle and store that in another #number.

To do this put a clock in a mag base and touch the probe end on the clock, find the lowest point, zero the clock and z axis then move the machine to touch the end of the spindle on the clock until it reads zero. Read the distance from the z axis DRO."

Do you want to measure to the tip of the probe or actually measure until the probe signal is tripped? By clock i assume you mean like a dial test indicator?

Looks like I need to find about 9 inch slip gauge block. I wonder how much that will cost if I can find one...

I have BT30 tooling, however all the tools have a bearing on them and stay in the turret. The turret is never clear of the spindle. I will have to see how I can get something up  there and if there is a part of the spindle not blocked by the turret. I dont recall.
A 4 inch block will never reach the spindle from the table. I will have to figure something else for that.
 I will have to jack my tool setter 4 inches extra off the table for my shortest tool to be able to hit it. I guess i am going to have to buy something to measure this...
In this scenario I guess there is no master tool and every tool is actual distance from spindle nose to tool tip?

56
I have a 3D probe that I plan to leave as tool 1. I am guessing this should also be my master tool?
I also plan to have another probe mounted as the tool heght setter on the back corner. This is the same probe but has a flat plate instead of the probe tip.
How do I do the Z calibration of the Probe set as tool 1? The tool height setter and the probe are spring loaded and require some amount of movement to trip.
If I try to do a Z calibration of the 3D Tool 1 probe to the tool height setter then the tool height setter will have some give before the probe trips.
I am just not sure how to do all this stuff so everything works out and when the real tools get measured off the tool height setter probe that it comes out right.
I am looking for advice or links to read how this should be done.
Right now I do not have the tool height setter mounted yet. All my tools will not reach it until I make something to lift it off the table higher. This is my next mission.

I think this is solved and likely what should be expected now with my setup.
Checking the "Charge pump runs in EStop" for the ESS seems to have gotten rid of the issue. I did clean up a few other settings as well while I was going over things with a fine tooth comb.

Now I get "E-Stop Cleared!" as my current message at boot up.

If you open the history, this is found, which I suspect would be considered normal for my setup:
-----ESS: Limit Switch triggered on
E-Stop cleared!
E-Stop condition!
E-Stop cleared!

Before it listed out many of the things using those limits and kinda random on the message it would end up on. It was always one of the ones related to the limit input and which one would come up last seemed somewhat random. Now it is always the same with a positive message at boot up. I think this is resolved.

Now if only someone could answer my question on how to setup an MPG for velocity mode.....that is the only thing left not resoled on my Mach4 upgrade at this point (until I start using it and want to change something).
For now I just set that setting to .01" incremental and 100% velocity unless someone posts a solution. I have emailed Machmotion, Artsoft, and posted here. No solution yet. Machmotion does not have a solution for it (and does not support my setup since it is Mach4 now). Artsoft first response was that they didn't seem to understand what I wanted to do for some reason. I am not sure if I will get another reply to my response or not.

Thanks!

I decided to buy a 1.0937" Master Setting Ring. It was only $35 shipped.

I just have a cheap probe right now, but I need something to perform the probe calibration procedure. Does anyone have a recommendation for something to buy?

I have an idea I will check tonight. I have the "Charge pump runs in EStop" unchecked in the ESS settings. Maybe my BoB could be holding the limit switch circuit hostage until it sees the ESS provide the charge pump signal?

This is from my BoB manual.

"Charge pump circuit and enable signals
When there is no E-stop condition and the Mach3 software based control is running
properly, Mach3 outputs a steady pulse stream to the IO6 breakout board. The IO6
receives this pulse stream and sends an enable signal to every axis mod jack
connector, on mod jack pin #4. It also enables all outputs of the IO6. If this pulse
stream is interrupted, the IO6 will correspondingly disable all outputs from the IO6.
This safety circuit prevents spurious outputs from the PC from producing unexpected
results.
The charge pump circuit energizes a relay that provides a pair of bare relay contacts,
and +5V & +24V enable signal for system integrators to use to implement other safety
measures. We also provide direct access to the charge pump signal. This phoenix
terminal is located on the Auxiliary Terminal Block. (See Figure 2)"

My E-stop and limit switches will kill the drives and stuff regardless of the ESS condition, so I am going to try turning this option on in the ESS so that it keeps the charge pump alive to see what happens.

I may need to rethink how I have my limit switches and E-stop wired with Mach4. Not sure yet. What I have now is very effective for safety though. The limit switches basically produce an E-Stop condition since they are in series with it.
