Uneven Quality

[jpleaner 0]

Hi All,

Does anyone have any ideas of why the Ultimaker 2 using ABS might create such a variation in quality across the one print. There are 5 identical components in this print with vast differences in print quality (seems to get worse going from the one it prints first to the last one). See attached photo and profile.

Thanks

Jason

Since the objects are so flat first think that comes to mind it's that the bed isn't properly level, making visible errors on the first layers.

Edit: Yeah the skirt on the ones of the bottom has diferent gaps between the lines than the others. That shows an uneven bed calibration.
