Sorry about the wait, it's been a busy couple of days, I'm in Finals week at the moment. Did it run before you made those changes to the firmware? The firmware I uploaded here in the Marlin .zip folder should be operational. Could you also send an image of your circuit board? If the X and Y don't move when plugged into their ports on the board, then something may be wired incorrectly. When you say it doesn't home, does it not move at all? Sounds to me like there might be an issue with your stepper drivers, I'd double-check that those are plugged into their ports properly and the voltages are at the correct range.
