You sound like you have the same issue I did. Are you sure of which stepper drivers you have? How many jumpers do you have installed under each driver? What is your steps per mm set to in the marlin comfiguration.h?
If you got the arduino, ramps, drivers from vicious it says that you should be ready to go but if you sourced your own stuff like me you may need to change some settings in your configuration.h.
