software files for ohmic and THC

I have QTPlasmaC loaded and I am getting close to finished with the setup. Question I have is are the 2 files required for Ohmic sensing and THC incorporated in the software package or do I need to load additional info? Also on the circuit diagram for the Hypersensing it shows a connection to the shield inputs connected to ground. On the other tables I built the table frame and ground were the same electrically, do I hook the table to the shield inputs of leave them unconnected?
Thanks for the help

THC is included in the QtPlasmaC configuration, if you use PnCconf or StepConf to build your config then it can be setup by them.

If using a THCAD for ohmic sensing then there is an ohmic.comp component included in the LinuxCNC package which has the code example just below your diagram.
linuxcnc.org/docs/devel/html/plasma/plas..._with_a_mesa_thcad_5
linuxcnc.org/docs/devel/html/man/man9/ohmic.9.html

I "think" the ground on the shield is not required, there are a lot of threads discussing this.

As a further option I think there is also an ohmic2.comp and an ohmic3.com floating around on the forum, what they do differently I don't really know.

Thanks Phil I still am in a learning curve but getting there with help
