I have recently bought a ramps 1.4 board because I wanted to install dual extruders. I plugged everything in the correct spots (some people accidentally plug it in the reset plug on the arduino, I didn't). I turn it on and nothing happens, the bottom of the Arduino gets REALLY hot and I don't know what to do. Could it be a bad board? I already tried brand new stepper drivers and I made sure I didn't install them the incorrect way, and nothing happens. I then took all the wires out and plugged the Arduino into the ramps and the power was also going to the ramps and it all lit up. I don't know what the problem is, faulty wiring ink.
