Hey guys! I have a problem that even the manufacturer don't know how to fix. I have 3 MakerBot Replicator 2, two of them are the younger version and one is the older one. Some files that I print, comes with a "gap" in the same place when they are printed by the two younger ones as the old always "close" these prints. Follows an illustrative photo. The piece on the left side was printed in the old and the right side - that has the gap - in the upper right corner. Any idea what might cause this? All files are corrected and all printers have the latest firmware update for the MakerBot. Thank you all for the help!
