I know why it won't connect, but I need help on what to fix, replace to get it back working. In short, I accedently left a bear wire of the power supply that runs the fan for the new E3D I just installed. It touched the power supply metal outside and everything stopped. The green light goes on, but the board will not connect. Ramps 1.4 with mega 2560 r3.
Any and all help would be appreciated.
