Hi, I built my first printer and when I start it up for the first time I get the following error…
Error:0
: Extruder switched off. MAXTEMP triggered !
Error:Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)
ok T:0.0 /0.0 B:0.0 /0.0 T0:0.0 /0.0 @:0 B@:0
and when i check the temperature it says…
ok T:453.1 /0.0 B:0.0 /0.0 T0:453.1 /0.0 @:0 B@:0
So my problem is the heater if reading 453 degrees without even being on and regardless of if the thermoster is plugged in or not. I’m well educated in the computer field but not electrical and wiring so I’m not sure what to do. I have a voltmeter and can do any troubleshooting necessary if someone could help me out with what I can do it’d be very much appreciated.

Your thermistor is shorted out or set wrong in the firmware. Ohm it out and see what the resistance is from the leads going to the board. Wait, the board says 453 if the thermistor is unplugged? What type of board?
yeah it was reading that unplugged as well. Was a firmware issue I just reloaded the firmware to it with the propper settings it said to and this issue was resolved.
HI
I have the same problem. No matter if the thermistor is plugged in or out, it says round about 453-495 degrees C. The Thermistor has 100 kohm and no shorts.
My board is a Geeetech GT2560. I use it in a Prusa I3. I use Marlin-Marlin v1 Firmware.
I already try to load a other firmware, but nothing happens there. So I loaded the the Marlin v1 again.
It seems to be a firmware problem, were can I change or repair this problem in the firmware?
@Chris_Jennison, what are your propper settings?
Best Regards
