    If your stepper will not move but just make a hum you may want to check the amps setting. It may be too low.

    On my 3d printer, which is similar in construction, I use a computer power supply rated at 360W which is about 30A. Take away the extruder heater and you are still left with more than 10A.

    I reassembled yesterday my 3d printer after is was in storage for months. It uses the RAMPS 1.4 board. When I finished none of the axes would home. Turned out I connected the limit switches in the wrong place. On the board there are six locations for the limit switches, two for each axis. I had put the connectors on the location for each axis rather than the first. When I changed it to the first it homed. Can it be that your y axis limit switch is also in the wrong location?
