temperature readings Gen7
June 03, 2012 02:24PM
I have 2 thermistors one for the bed and one for the extruder both are of the 100K type

But I have this strange thing. The one gives me a 23C reading (pretty close to the 20C I measure with my thermometer) and the other one gives me a 357C reading.

At first I thought the second one needed a custom table, but it didnt really work

So I made this experiment. I set them both as type 1 in my repetier firmware and excahnged them. And I found out that the one in temp2 molex shows always 357 , while the one on temp1 molex shows always 23C

is there some problem with my board? both resistors are 4,7KΩ

Yes there is a problem with the board assuming the firmware is configured to use the correct pin for temp2.
