I would make some changes in the hal file.

Change:

setp hm2_7i76e.0.dpll.01.timer-us -50

to:

setp hm2_7i76e.0.dpll.01.timer-us -200

and change all joint PID "P" terms to 666

If you can use any Linux x86_64 on it, then download the official ISO and try installing it, but might have issues with RT kernel running in a VM.
You can try Debian 12.x or Linux Mint Debian Edition 6, and if they work just install LinuxCNC with
sudo apt install linuxcnc-uspace
This will also install the RT kernel, but it will not be the default one, so LinuxCNC should work OK in SIM mode.
 

I have been looking at this response for almost a whole day, and I still can't figure out what part of it applies to my question.

Yeah, the GUIs don't list all possible connections so you
need to connect these by directly editing the hal files.

Thanks for your patience.
I get that I can find all the available pins using the methods above.
What I don't get is that when I use mesaCT or PNCConf to create ini and .hal files and have selected say channel 0 for the X encoder, The physical pins that will be used don't show up the hal file.
Its to me like when you make the selection in the gui, some things are automatically known like the pins, and the hal file doesn't need to show all of them, just ones you might need to edit.
So the hal file isn't the place to look for the full details of a setup right back to pins.
I will learn this system...

The hal file is what connects things (it does not show all possible pins) ,
so to use an encoder input, you would do something like this:

net min-x <= hm2_7i92.0.encoder.01.input-a

You can use halshow to browse pins and parameters:

 


or list all pins/parameters by running this command:

halcmd show all

from a terminal window when LinuxCNC is running.

You can also

halcmd show all > all.txt

to create a copy/paste donor file when editing hal files

if you just want hardware pins/parameters

halcmd show all hm2

will do

If you just want encoder pins/parameters.

halcmd show all *encoder*

or

halcmd show pin *encoder*

if you just want to see encoder pins.

Maybe post your hal and ini files.

I guess that's the bit I am missing.
In the hal file, there are no "input-a" anything for the X,Y and Z encoders so I don't get how lcnc knows what anything is connected to.

Sorry.
