Where is the d1 diode in ramps 1.4? Answered

Hello there. First I apologize for my bad english. I have a 3D printer. But Arduino did smoke 2 times. I tried the engines. But the last time I tried to test the extruder engine, there was smoke. Arduino's voltage regulator burned. I did some research. I had to remove the D1 diode. I could not find it because I did not have much information.

Under the stepper driver boards, I had a dry joint on mine resulting in no power to the Mega2560.

Mine was an old school 1N4007 but yours is most likely the SMT component that I have circled in red.
