    So that sounds like:
    1) the stepper that turns the exrtuder is weak/bad
    or
    2) The stepper driver that makes the stepper go is weak/bad
    or
    3) the ramps board that drives the stepper driver is bad

    It a worst possible case the Arduino is bad, but that seems unlikely.

    You need to test the stepper and driver by disconnecting the extruder stepper from the RAMPS and putting it on another stepper output connector (like X or Y or one of the Z) and then testing by manually stepping that axis and see if the extruder stepper (and extruder gears) now turn. For example if you hook the extruder stepper up to the X axis on the RAMPS and you then power up and connect and have the software manually step the X axis does the extruder stepper turn as it should? If not, bad stepper. Period. If it DOES turn correctly it is probably the cheap stepper driver daughter card on the RAMPS that is bad. They really are easy to swap and cheap. Of course if you are under warranty you can get replacements from Robo

    Those are examples, shop around (I am not promoting a specific seller -- I just found those via search).

    However I have used a kit like that (not sure if it was that seller) and they are excellent.
