Adding additional Temp Sensors to Duet3 mini
-
Hi guys, Ive used up my dedicated temp0,1,2 inputs on my Duet3 mini. Just wondering if anyone has wired their own resistor network to use other inputs such as io0.in - io6.in. I looked at this schematic here: https://github.com/Duet3D/Hardware/blob/master/Duet3/Duet3_MB6HC_schematic_v1.0.pdf - and found there is already a resistor network implemented, probably to protect the chip from overvoltage situations, so Im thinking adding another network on top of this will have some skewed readings. Any input would be appreciated!

How many more are you planning on adding? You could use the daughterboard expansions to add up to 4 more PT100/k type thermocouples and should be a lot easier than creating the network you’re describing.
