I finally got an actual print out of my printer, but it just suddenly started reporting 0C(MINTEMP) for the extruder temp sensor later that night while i left it idle. I checked both of the temp sensors which report 100k Ohms of resistance. Checked marlin(i’m running v1.0.5 r-2) and the sensor settings are correct. I tried plugging a backup temp sensor into the port which had the old temp sensor, and it still reports MINTEMP. Any suggestions?

Side note: i had to redo the connection on the bed sensor by taping aluminum foil to the + side, and for some reason it fixed the bed temp sensor(it reads correctly now). The extruder one still doesnt

Edit: I would like to use the other temp sensor port i have, bit i dont know how to edit the pins.h or any of that stuff.
