I tried my hand at a thermocouple today. Turns out it was super simple when using a linear converter. The biggest challenge was adding some more ADC channels to the DT.

Can you add details about how you got this working please?
I have a Rev B3 board with a E3D V6 at the moment but I am looking at what is needed for a thermocouple to expand the temp range for more exotic filaments.

It looks like you need a interface board to convert the mV thermocouple output to a 0-5 analog output for the replicape but what happens on the “firmware” side to scale this to the correct temps?

Thanks

Hi! You need to implement the class for the sensor you have. Is it pt100? You might need to divide the voltage down so it fits in the 0-1.8V range as well.

I haven’t got any parts yet. I prefer to work it all out before buying stuff if possible.

I’ve never done anything in python so might need a bit of help there.
