Solved found my heated bed problem, but what now....

So I seem to have found the problem with the heated bed... printer arrived only last tuesday... looking at the pics, what to do now???? I never heated it more than 70 degrees, I kept everything at the default settings in matter control

 

I am tempted to replace the connector, but does anyone know if it could be the ramps board? i pulled out the negative power for the heated bed on the board, was clean as can be,no signs of shorting out.... I have the latest firmware on the board from shortly after unboxing it....

 

I ended up just soldering the wires directly to each other. If I need to remove it in the future, Ill just unplug it from the board. As long as the problem was not on the Ramps board....Hoping that is not the case.

 

Sometimes a short like that can damage the ramps. There's only 2 components on the heater supply, the mosfet and the polyfuse. It may also have blown a trace in addition to the other components.

That's a bummer man. Especially since you just use it at 70C that's very strange.

 

seems ok after soldering, Robo is sending out a replacment cable I can add on once I get it.... All is right in the world again

 

Yeah i had almost the exact same problem. I dont believe its the heat from the bed causing the damage to the plug.

In my case i suspect the failed MOSFET caused the damage to the plug. My bed would heat uncontrolled, suggesting the MOSFET failed open, possibly causing an over current/voltage in the power to the bed, resulting in the overheating/damage to the plug. When i looked at the solder joint on the MOSFET one joint did look suspect as though overheated, and replacing it did resolve the uncontrolled heating.

I think I got a pack of 5 for about $10.

 

I was told by Robo that it was the connector on the bed, when the bed moves back and forth it can cause shorts in the connector because of the movement. My Ramps board had all good connections, so it wasn't there.

 

If you do replace it yourself use anderson powerpole connectors off of Amazon. You can get various amperages.

 

the new one wires differently, so its not an issue.... Thanks!!
