Is there any way to use Pncconf Wizard to set up 7i97T with 7i73 pendant board?

I have been trying to get my 7i97T to work with a 7i73 so I can use an MPG and a few other local input buttons. I've tried Mesa CT but it will not work with the 7i73, no option to flash that card. So I tried Pncconf and it does not build a good file for the 7i97T. I tried the board discover option and it appears to work but when i actually try to launch the build file it give me a bunch of errors on the 7i73. If I change the I/O of the error pin to not used it just errors out on the next pin... Another issue that is also related and why I'm attempting to use the Pncconf is that I need to install a tool setter and touch probe. Pncconf would be the way to go but i cant get it to work with me. Has any one run into this before?

There is an experimental version of pncconf (for LinuxCNC 2.10 only) that supports the 7I97T in this thread:

forum.linuxcnc.org/plasmac/55286-servo-d...ofit?start=10#331289

Note that there is no specific firmware needed to support the 7I73

There's also a sample 7I97T configuration to which  7I73 support could be added:

To list 7i73 pin and parameter names:

halcmd show all | grep 7i73


while LinuxCNC is running

I really don't even need to use the 7i73, all I am really trying to do is add a probe input and set up this MPG for my 7i97T. I really don't know how to add custom components to hal and ini files from scratch. I will admit that I do need to read up on the process...

Adding a simple probe input does not require adding any components, basically just
making some connections in the hal file, something like:

 net probe hm2_7i97.inmux.00.input-15 =>  motion.probe-input

 or perhaps

net probe hm2_7i97.inmux.00.input-15-not =>  motion.probe-input

depending on the probe polarity.

Adding a MPG will typically require at least one components as a mux component
is often used to select between jog increments.

Searching the forum for MPG will finds a number of MPG implementations and hal file examples.
