hey, I had a similar issue. Try to remove all the stepper drivers, and any other connected stuff. When you have only the ramps connected to the arduino board, try to connect to it via repetierhost. Another way is to see what happens is opening the serial port in arduino ide, and check what it writes there… Hope this helps, Cheers
