This is what i followed. Everything went together smoothly and i am able to communicate with the arduino. I have installed marlin firmware (Was getting a "Printer stopped due to errors" But i fixed that by disabling the thermistor for now.). The power supply will only stay on when the usb is powered also. I have installed the jumper on the power supply so it will turn on properly if it is not plugged into the reprap but once i plug it in and try to turn it on it starts and immediately turns off.
