Hi
I have has a Chinese I3 Clone for about six months.
Everything was fine until I extinguished the fire on the main connector, which I believe is a common problem with this board, so I decided to replace it with a Arduino/Ramps setup.
I have a problem. Despite the fact that the controller display works on the burnt boar when powered from the USB, i.e. it is working fine, I cannot get it to light from the Ramps board.
I presume it is something simple I am missing.
I would appreciate any assistance.
Thanks
