New Project with Mesa 7I96 and THCAD-05

The fist pic seems to indicate that the ohmic component has not loaded.

You can access encoder B if you select the corect firmware in the Configuration Page shown in the second pic. It wont help though as ohmic is not included in PnCconf.

ohmic-enable would normally be used to turn on any relays used to enaable ohmic senseing, I don't know if the ohmic3 component uses it or not.

Can you post your current machine and custom hal files.

The ohmic3.comp should be loaded per the loadrt command in his custom.hal
The ini file shared showed that custom.hal was being loaded.
It should be named ohmicsense by that file.
As with any missing pin, comment the offending line out, and review halshow to check the component is loaded and what the pin name is.

Ohmic3 does not need the ohmic-enable signal

here is the last info you asked for in a Zip file, I hope we can work this out as it seems to be the last huddle.  I do thank you all for your time and knowledge.  I am here to be your eyes and hands on the ground here
 

Just a thought with my limited knowledge it looks to me that this Pncconf may be setup to use a different type of Ohmic sensor. Like a feather touch or other brand, These would use a input signal to the 7I76E board. The Pncconf input pins can be selected for a Ohmic sensor other then the Encoder B.

So the installation of ohmic3.comp was discussed here in this thread here
forum.linuxcnc.org/38-general-linuxcnc-q...-05?start=290#212684
A link was provided to this post where it could be downloaded
forum.linuxcnc.org/plasmac/38848-hyperse...ons?start=210#175839

From what I could see you installed all of this because I would have expected an error about ohmic3.comp not found before the pin was not found.
Can you open halshow then open the pins part of the tree and confirm ohmicsense exists?
If we get that far, can you then open the ohmicsense tree  and share a screen dump of its pins?

Yes, originally Plasmac was using a circuit using relays which is described in the plasma primer here
linuxcnc.org/docs/devel/html/plasma/plas...r.html#ohmic-sensing

Then PCW came up with the idea that became hypersensing with ohmic3.comp
