Ender 3 X-axis values are not correct So I just got the Ender 3 and have been trying to print out a part. However, I noticed the printer is trying to print the part, which should be centered in the bed, on the left side. 

I performed the auto home, leveling procedures, prior to execution, but it still wants to print it on the left side. 

I checked the values it thinks it has for X, but they are about 60 mm to high (i.e. from the control/move axis menu, I move it towards the zero position and when it touches the switch, it still thinks its around 65-70 mm in the positive direction).

I have tried the good old power cycle, but each time it seems to get worse printing closer and closer to the edge. I am sure that I must have fudged something up. Anyone know how to fix the mismatched position? 

Thanks for any advice!
So the issues with the digital display values, was caused by the X-axis binding up and not advancing. I had to move the axis via the control panel in the positive direction and noticed once it got about half-way out, it wouldn't advance for like two or more steps.

On the control panel, it said I was 235 mm out from the home position, but in reality I was more around the midway point. When I would move it back to the home position the read-out still displayed that I was offset from the home position in the positive direction.

To fix it I tore it down and reconstructed it (made sure everything was plumb and level), I also flipped the belt in the opposite direction (teeth down, so that the stepper pulley grips the belt teeth).
