Let’s talk thermocouplers!
I need HELP!!!

In big industry they are the standard over thermisters for accuracy, range, and most importantly reliability/durability. I used a thermocoupler for my bed temp when I used to have a stand alone PID controller with SSR. It worked great but I got rid of that setup to eliminate clutter when I got my Azteeg x3 pro, which has two thermocoupler inputs. That is where I’m stuck. I had to use a thermister while I try to figure it out but really want to use my thermocouplers.

I found the necessary selection in marlin for thermocouplers but have no idea how to get the corresponding input to be referenced for the bed…

I found this bit if I understand correctly, it has a separate arduino with thermocouple amplifier. My board has it built in, so not sure where or what I need for the sketch

Finally figured it out! Still have some bouncing in the reading but it is accurate. Now to figure out if I can tune this thing properly
