Err: MINTEMP  

Re: Err: MINTEMP

That is certainly a live chat and email to technical.

I got a false reading of the nozzle temp when I had done the screw up on the heat block a little too tight. Read 700C odd so might just be worth having a look at the screw on the heat block that holds the thermister and maybe unscrewing it just a little. If no change then screw back as was. That said, thats if you have the thermister with the screw on it.

Re: Err: MINTEMP

That is what I love about this printer, failures that forces to think about how it is designed.

I found the cause! The temperature sensor connector on the extruder got disconnected when I wired all the cables. What I do not understand is why it gave a temperature of 14 degrees Celsius? Why was this not 0 degrees? Or 255 degrees?

Re: Err: MINTEMP

Beacuse of the characteristics of the sensor. It is thermistor with specific electric resistance curve based on temperature.
14°C is given by resistance equal to infinity.
I hope you understand my explanation, I'm far beyond my English skill explaining this.

Explains a lot of your comments then 🙄

Re: Err: MINTEMP

Ben, thanks for your constructive comment here. If I am wrong, how about writing better explanation instead of directing me to Czech section?

Just trying to be like you man 😆 😆 😆 😆 😆 😆

Re: Err: MINTEMP

I think that the actual simple explanation is that when the thermistor is not connected, the processor interpolates the open circuit reading as 14 degrees..

The thermistor is part of a small circuit with a 4.7KOhm pull up resistor when the thermistor is OC, the full 5V is applied to the processor input pin, which is then interpreted by the ADC as 14 degrees.
