#Arduino mega 3d printer pinout serial#

When I connect 12V (0.8A) to the power connector, the big capacitors near the power connector hold 12V (according to the circuit of the Arduino Mega it is before the regulator) and the other big capacitor hold 1.7V (need to be 5V). I want to know if it's the only component that have damage. It's seems that the AMS1117 voltage regulator that supposed to put out 5V is damage.

so I only put out the power from the Ramps of the 3D Printer and put it on my Ramps.Īfter what happened I call the guy that help us to build this particular 3D Printer and he ask if we put out D1 diode from the Ramps as he do to his Ramps (that is used on the 3D Printer) I connected it to 24V of 3D Printer that use Ramps etc. It connected to the Ramps board with graphic LCD and only one driver to the X motor. If you used the arduino to switch the 24v you may have fried the beast.

is there a way to upload to this board with help of other board? (Arduino micro etc.).

I connected the 5+ to the 5V/GND on the power pins and the led was lighted as usual. I try to connect 12V to the power connector of the Mega to see if it will work but got not light on the power led.

I disconnected the Ramps, reset my PC and nothing, I can't see serial COM of the Mega on the Device Manager (Win7), I connected another Mega and it's work good so it's seems that something burn in my Arduino card. I see the merlin run on the LCD just like before.īut, now I can't upload any sketches to the Arduino Mega. I connected only the Ramps/Mega with the LCD to the PC (without the motor/Power supply) and it's seems to work good. The LCD got crazy so I disconnect it to see if it damaged. I tried to connect it to a 3D printer that use 24V (and ramps etc) to test one of the motor of it to see if the ramps/mega work good etc. I bought kit o Mega (R3) with Ramps and Graphic LCD, upload the Blink program -> good.
