Nozzle temperature not correct
Hello everyone,
I more or less successfully converted my MK4 to a Core One today.However, I'm now having the problem that the nozzle temperature is no longer being detected. The sensor always shows 25°C. Even when I heat it up, it stays that way.I've already replaced the sensor and installed the old "main cable" for testing, but the result is always the same.
What's really strange is that the electronics detects when I unplug the sensor.
This means: The display is 25°C, no matter how I heat the sensor. If I unplug the sensor, I get a message saying it needs to be checked. But the display remains at 25°C.
Maybe someone has already encountered this problem, or at least an idea.
Thanks, Dieter
RE: Nozzle temperature not correct
No firsthand knowledge but the very first (maybe so obvious you already did it and just didn't write about it) is to check all of the connections to ensure that you have all of the various temperature sensors a) connected to the correct locations and b) the connectors are firmly seated.

Steve

It's possible the thermistor in the heat block is bad. Over tightening the grub screw can crush damage it. Try swapping it out for a different one.
Did you run a heater calibration test recently?

Checked everything double. All connections done and on the right place. Have replaced the thermistor with a new one, used the 'old main cable' which works before.

The nozzle is heating. Calibration ist stopping since the temperature is not raising, even the nozzle is getting hot.

Do you have a multimeter with the thermocouple input?
I am having different trouble with the hot end temperature and used a thermocouple to see if things are heating and what temperature they really are, I got mine with a cheap multimeter from Amazon. I just put the end of the thermocouple under the silicone sock so it was in contact with the heat block.
Don't forget to disable the motors if you are putting your hand inside with it powered up.
