The print bed doesn´t heat anymore.

The connector was burned. How do I know the source of the problem : it is the motherboard or the resistor?

Thanks in advance,

Nelson

Most likely just a bad connector.  The heatbed uses a lot of power and those connectors are not the best.  Just cut it off and crimp a new one on.

+1, plus replace the header on the PCB as well as it most likely has carbon buildup which will cause the new connector to overheat as well due to bad/intermittent connections.

Hi everyone,

I´ve already check the print bed and it's heating... (procedure: connect the bed heater to the extruder pins and select "heat extruder." If the bed still doesn't heat up, it's the resistor, if it does, it's the board), but I want to make sure the problem is the board before I buy a new. How do I assure that?

thanks.

Did you read the responses to your original post?

I am guessing there's a little language barrier here.
I would guess you just have enough carbon and corrosion on the pins to pevent a good connection.  You should be able to clean those up good and be fine.  Unless they melted the solder joints on the board.  Even then they could easily be soldered back on.
