Topic: Help With Arduino Burning Up (Davinci to Ramps Conversion)

Hello all,

So I have been undergoing the process of converting my davinci 1.0 to a ramps arduino mega combo. I had wired up just about everything (steppers, thermistor, hot end, endstops) and was having an issue feeding the filament smoothly to the hotend (it was an aftermarket hotend) so I decided to revert back to the stock hotend. So I wired up the shock hotend\extruder and its thermistor and when I went to connect the computer to repetier on the pc I smelt smoke and saw smoke rising out of the board. I did not see where the smoke had risen from but assumed that it was from the ramps board due to that being the only thing I had touched so I ordered a replacement, transferred over the cables and was getting no response from the printer so I replaced the arduino mega and when I went to plug it in smoking again this time I saw exactly where it was coming from it was the arduino and I have attached a screen shot of the exact component. I am hoping someone can tell me what the component is, whether its replaceable and what in the world keep be causing it to burn up??

Thank you to all who read this and attempt to help ahead of time <3

According to google it's a 5 volt regulator..

Is it possible you are drawing the ramps power thru your arduino power?

Re: Help With Arduino Burning Up (Davinci to Ramps Conversion)

what part is smoking and is it a real arduino or knock off?

the knock offs in my experience will let the smoke out if the power supply is greater than 12v.  check that.  replacing the davinci power supply wouldnt be that bad of an idea.  my ramps conversion flickers the interior led light when both extruder and bed are at 100%

If you look at his pic it shows what smoked. Look at the regulator between the connectors and you can see the damage. I had one do this but the reason was the jumper on the Ramps that dictates how Arduino gets power... As said these regulators are cheap and can't stand any over voltage on their input.

I replaced the regulator and now the board works fine.

Well I did order a 5 pack that will be here tomorrow so hopefully they will be of better quality and the boards will still be useable. Is there anyway to test that this is the issue on the second board? the first arduino that burnt up has no signs like the one posted no visible traces of damage so I am wondering with a multimeter is there a way to test that the regulator is the culprit as well? Also the jumper on the ramps board that dictates where the arduino gets power is there any way to upgrade this to make it more accurate?

There is no way to test the regulator other than using it. They are not so much defective as they just are cheap and can't stand anything over 12 volts going into them.

In regards to the jumper on the RAMPS it is not so much an upgrade as it to make sure it is there and in the right position. See the image for reference.

Your telling me that the jumper is required? I dont have a jumper on my ramps board at all. so its not in either position. I also couldnt find much on the positioning when searching for ramps jumper position.

Do you have the jumpers under the steppers installed? I don't know that all of the RAMPS need that jumper but one of mine did. With it not installed I had the exact same thing happen to me that happened to your arduino.
