Thermistors

How can you tell what thermistor you have?

Also, why does it keep saying thermistor decoupled?

Repetier

Well when you buy a thermistor they should tell you what you buy.

Decoupled means heater and thermistor are not responding as expected. See log for mor einformation why you get it. It might be at beginning when it does not heat up also you are powering 100% and later when you have reached target temperature it might be temperature leaving allowed corridor.

Ya but it was never recordered and the project was passed on to me. Where is the log at?

Log is at bottom of Repetier-Host. Disable easy mode to be able to open it.

Okay so I had the log open the whole time lol.

So what the error that is popping up is "Error: One heater seems decoupled from thermistor - disabling all for safety."

Then the next line says "Error: Temp. raised to slow. Rise = 0.00 after 13073 ms."

The weird thing is when we are trying to heat the head, it is getting hot. After 13 seconds it is too hot to touch.

When we run extruder 1 it works perfectly fine. but extruder 2 gives that error.

Seems like you have set a thermistor for extruder 2 that is not connected to that extruder. Maybe the bed thermsitor. So firmware sees no temp. raise because the thermistor is not getting hot since it is not the one on extruder.
