    Then you need to loosen the drive cog from the motor shaft (they are held on with small allen set screws). Raise/lower it and test moving the belt until the belt stays in the center of the spindle.
    (and no I can't really see it there... too dim)

    I'd suggest using loctite when you tighten it back up as well.

    I figured out that is it. Any tips to get it center? I thought it was tightened it up and it slid back to the top.

    You just need to experiment with the position of the drive cog on the motor shaft. You want it so that the belt is centered in the pinions.
    Mine for example was too low. I had to raise the drive cog about 1/8 of an inch higher on the motor shaft to keep the belt centered.

    If that still doesn't work, try tightening the belt more, I had to tighten it more than I would have thought.

    That is exactly how I describe the belt tension on all of the belts :)
    They need to be tighter than I would have thought.
