Hello,

I have a problem on the heated bed of my Rostock 301.
This printer have more than 8 months old and it was working well... now, the following problem is happening:

When I request it to heat to 110 C, the heated bed starts to heat... But, in a random moment, the heated bed shut down and stops heating.

See the following video displaying the problem.


What I tryed:

* did the soldering again of the heated bed
* replaced the thermistor of the heated bed
* checked all wires and connectors

How to proced to solve or identify the reason of this problem?

Thank you in advance.

Hi, you can try to check if the wiring of the hot bed is fully connected.
If you are fully connected, you can check if the hot bed line is damaged.
Or provide a specific video so that we can solve the problem better.
