Melted Heat Bed Thermal Block  

Re: Melted Heat Bed Thermal Block

Hi Nathan

There are many posts about this on the forum and Josef has also commented.

There is very little that you can do about this, as both plug and socket will require replacing which is not an easy task. The best you can do is to cut the heater leads and solder them to the underside of the board.

As to why this has happened, during build, the screws were not sufficiently tightened, the plug was not properly seated in the socket or there was some dirt/dust in the connector, which caused a high-resistance joint, which in turn generates a lot of heat and melts the plastic plug/socket.

In any event, soldering the wires directly to the board removes the two mechanical connection points where high-resistance can occur so it is the best connection method available.

Hi Peter,

Thanks so much, would there be any benefit to desoldering the melted block off the board or should I just solder the cables straight to the underside without touching the block?

Thanks,
Nathan

I don't think that there would be any benefit from removing the existing connector block; indeed if you attempted to do that, you could end up damaging some of the tracks, resulting in you having to purchase a new RAMBo.

Peter,

Thanks, I just wanted to double check before soldering the wires.
