As you can see the nut is below the trap on the Belt Idler side, this occurs after every print and this results in this side being higher then then the right side (where the Z axis end-stop is located)​. I have to unscrew it re-seat it and then level the bed after every print. Any idea what could be causing it?. I did note that the Derlin's were tighter then on the other side so I loosened them up. I did contact colin and said it probably the gcode from Simple3D an suggested I just stick with SliC3R 0.99.
Have you attempted to square the X Axis to the Y Axis? I don't know if this would solve your issue, but if the X Axis is skewed then it may cause this issue.

Below is a picture of what I do to level my X and Y Axis:

I am measuring the distance between the Y Axis crossbar and the X Axis crossbar using a combination square. I do this on each crossbar for the Y Axis and ensure they measure the same distance apart. This ensures that the X Axis and Y Axis are as close to orthogonal as possible. I would check this first.

I can ensure you the G Code with S3D is not causing this.
