I get the error even if the thermistors are plugged in or not, and if tried swapping thermistors, reprogramming the pins and using T2, and Ive alby melcher - RAMPS Electronics
I am also having this error. Both my bed and hot end worked fine and now both just MAXTEMP. thermistors both show ~110K resistance when checked with multimeter. Is there anything else to check either on the board or the thermistors to see if they are the problem?by melcher - Sanguino(lolu)
