New Project with Mesa 7I96 and THCAD-05

Thats great.
If you do the changes to custom.hal that Phill suggests, you should be good.
if you get an error something like  "pin is already linked' you might need to add this as right before those 2 lines.

Ok copied the 2 lines to the custom Hal below the other lines talking about the Ohmic sense. Would not start QTPlasmaC did not like the last of the 2 lines removed and started QTPlasmaC fine not change in the operation.
I have attached the error message and the log file. 
 
 
 

will do in the morning I did get the error message

You need to do the unlink line that Rod posted.

Great progress. Should be good with the unlinkp in the morning!

Ok with the 3 lines in the custom Hal QTPlasmaC starts  When I look at the Hal show for the Ohmic sense values the attached screen shop will explain what happens.  The Arc-on changes from red to yellow when the switch is pressed.  The Ohmic check does not change when pressed and the switch is pressed.  The probe just moves down and up with nothing changing when the switch is pressed.
 

I am not sure what switch you are referring to.

I have a micro switch acting like the torch tip and metal contacts, switch closes same as torch touching the metal.

What does the switch connect to?
