Hi all,

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.
Thanks

Hi，If your hot end is not heating properly,
You can check if your wiring is fully connected.
If the hot end wiring is fully connected, you can measure the thermistor at the hot end.
