4. use existing analog inputs on Mesa 7i84.

Cr@p, forgot about that, getting to damn old, sorry.

It looks to me that all the graphics previews are a copy of what Axis has with some variations.

Yes, with the exeption of 'Probe Basic'.

It's a very deep and cornfusing rabbit hole for sure.

Yes, I know canon = StatCanon(...) but what does StatCanon do?

Well, I'm certainly not the python expert but if we follow the trail then it seems to initialize these two classes which can be found in /lib/python/rs274/glcanon.py and /lib/python/rs274/interpret.pyWhich are used to set up the preview window depending on the geometry of the config and also (I guess) the tool preview. As for the more intricate details of the code, I'm probably not the right person to answer. 

You will need new firmware for your 7i92. I'm not to sure whether the 7i92 can support 9 stepgens, 2 Spindle encoders with index and 2 smart serial ports. I might be wrong about this, but I think I've heard Pete mention that there is some limitations with the 7i92. This bit struck out in red is incorrect see Pete's post below for correction.

Something that configures the 7i92 that has a 7i76 on one port and a config that matches the 7i78. (possible a Bob type config)

The 7i78 is just a card that conditions the electrical signals from the 7i92, it has no "smarts" it is passive. The FPGA on the port it is connected to provides all the signals.

The 7i76 has 1 encoder with index that is suitable for a spindle and 2 encoders that are suitable for a low speed encoder, eg a MPG. These are enabled by setting the smart serial to mode 2.

It can be a little confusing.
The 7i76 stepper connections and encoder with index & analog spindle controller are controlled directly by the FPGA on the 7i92. The other functions 48 bits of I\O, low speed MPG inputs and analog in are controlled via a MCU on the 7i76 that connects via a smart serial interface that is routed on the PCB. It also has a second smart serial port that is exposed via the connectors.
The 7i78 stepper connections and encoder with index & analog spindle controller are controlled directly by the FPGA on the 7i92. Similar to the 7i76.
And of course the 7i84 is connected via the smart serial interface and has a MCU on the board that controls the I\O.
It took me a while to figure this out and it really kicked in when I started playing with the FPGA firmwares.

=:o( I'm sorry, but your explanation is not the answer that could help me. Or I am misunderstanding and misinterpreting your answer ...
I don't think I'm asking the right question, or my questions are interpreted?
So again ...

To help me:
Can and or do you want to write a HAL/INI file for me and my CNC portal milling machine?

If so, what informations do you need?

If not,

the second possibility to help me:
Can and/or do you want to write me which terms I need to assign to the pins from the pulldown menus of the PncConf. Please watch my video per Link
www.dropbox.com/scl/fi/j62sg1yh12hca8g03...dbu&st=cnasz00z&dl=0

I need the correct assignment terms from the pull-down menus in PncConf that match my data sheet for the contact assignment.

To respond to your answer, if I understand it correctly.
I am using Visual Studio Code to create, read, emulate an save HAL and INI files.
Are you referring to this or a similar programm?

Git does not require root permissions (sudo)
Using halcompile does.
Installing software from repositories with apt install needs sudo apt install

Not understood at all, how can I configure the 7i78?

Auf jeden Fall den pncconf verwenden um eine XYZA Konfiguration zu erstellen (mehr als 4 Achse gehen da glaube ich nicht), dann erst mal diese 4 Achsen zum laufen bringen. Erst wenn das geht die 5. Achse manuell in der hal/ini hinzufügen.

Schau mal hier rein, der hat so einiges an Erklärvideos:

Vielen Dank für deine Antwort

Was ist der beste Weg um die eigene Maschine einzurichten? Starten auf Basis der Simulation oder besser über pconf eine 3 Achs Maschine erstellen und diese dann in den HAL Dateien anpassen? Oder was ganz anderes? 
Kannst du ein Tutorial oder ähnliches zum Thema HAL und ini empfehlen? 

Grüße
Manuel 

hello I successfully completed the first phase but I still have the DRO inactive. 7i77 card does not flash green and stays redsee photos.Thank you again for your help.

You'll have to fix this

Debug file information:
Note: Using POSIX realtime
hm2/hm2_7i92.0: config.num_encoders=2, but only 1 are available, not loading driver

Which would be related to the actual firmware.
The 7i78 is more like a regular parallel port breakout card, and does not have a MCU or FPGA that would announce it's config.

Not positive but I think 'gantry.comp' is an outdated solution (2014) to drive multiple joints which was necessary before joints/axes were separated in Linuxcnc Version 2.8+.

When the homing is done, I turn off (comment out) from the hal and ini and using just HOME_ABSOLUTE_ENCODER = 2, so no movement on axis.

Seems a bit suboptimal to have to edit the ini file after homing. If I remember correctly, the custom homing module creates hal pins for each joint that let you choose whether to use custom homing (ie drive internal) or default homing (ie HOME_ABSOLUTE_ENCODER = 2) but I have not tested that.

As for jogging, you should be able to handle that from hal using 'motion.jog-inhibit' pin.

ok.

But then what is the use of gantry component, request for explanation for my understanding at least.
