Per the image below with cura 15.4 the centered print both shifted to the bottom of the print bed for the first few passes and then did not build the proper internal structure of the bracket. the top loops were then skewed to the top of the bed.  the 2nd print in the corner was using cura 3.1 and the first few passes like usual skewed off towards the bottom but it seemed to start printing normally after that.  I am trying to determine if it is a hardware calibration issue or bad firmware on the printer. any suggestions on whats going on would be appreciated. For some reason the image flipped 180 when posting.
