Hi, the temperature is shown as hot end is 0,
What you should check is whether the thermistor connection on the hot end is loose,
If you want to measure the resistance of a hotbed,
It can measure blue-green lines.

Hi,

I have change my temperature sensor of my nozzle.
So my nozzle it's OK.
Now I heated my nozzle and my bed. But my bed up to 60°C. It's stable for a little moment then it's free fall.

Do you know my problem?

Thank you,

Hi, Is the hot bed heating automatically after turning on the printer?
You can try to unplug the hot-bed wire from the motherboard and check the temperature indicator.
If -14 is displayed, the thermistor of the hot bed needs to be measured.

If the temperature drops after heating, you can check whether the thermistor on the hot bed is loose.

After new test.
I heat just my bed. But my bed don't heat and I have the error : Error : Nozzle 0-TEMP The heating element is out of order! Please kill the job manually.

Hi, Check whether the thermal bed thermistor is loose.
Then measure thermistors on the hot bed.

Sorry,

How to check whether the thermal bed thermistor is loose?

And how to measure thermistors on the hot bed?

you can use the multimeter to measure the blue-green line of a hot bed.

With printer on or off?

In ohm meter?

when the printer is off
and you can check.

I have 005 ohm.
On the multimeter, I am on 2000k ohm
