Hi, I didn't find any thread about this issue, then I ask for help hier
The printer works well and then, randomly After a few minutes the hotend stops heating. Temperature goes to 0 gradually and Display shows for example EXTRUDER TEMP 200/0, while before was 200/200
I tried 3 times and always have the same Problem. Extruder doesn't work anymore after a few minutes because of the temperature of the hotend.
What could be the problem?

Have you tried to check the wiring of Extruder?

Problems started last week, before that was all right.
I checked the wiring :

PS: printer OFF

It seems not normal（Normal is 1~6Ω）

Are you saying, that the problem is on the wiring?
If yes, is there a video explaining how to repair/change the cables?

What are you saying?
I have a broken cable? How can I fix it please?

It seems you need a new heating bar
