FYI, I loaded up the Factory file in Simplify3D.
If you use AutoLeveling, make sure you add a G29 to the start gcode.
VERY IMPORTANT!! I don't know what all is in the end Gcode, but it caused my Z to go up and my spring coupler stretched out. I'm surprised it didn't snap the motor mount. I think it reached the top and tried to keep going a bit further, so be careful about this.
