X axis homing issue

Hi, after letting my Press sitting in the corner for a while the x axis isn't homing. The extruder doesn't move to the right(toward the x stop) at all, instead when I try to home the x axis it moves about 10 mm to the left then stops! Then it sets that as home. I was able to move it to the right with the manual control. So I tried turning of the printer and moving the extruder manually to the end stop, then I started it up and pressed home all, after moving to the left and popping down the probe it set that place as home for the x axis, keeping it from moving back to the center to home the z. I'm using Repetier Host and I've also tried using Matter Control. I've re-flashed the firmware but no success. Any help would be very appreciated.
