My Replicator 2 has been printing flawlessly for a long time and them the hot end unit went bad so I ordered a new one and installed it and now all my prints have a gap between the shell and the infill. The odd thing is the gap is only in one axis. I printed the same part twice (at the same time and turned on 90 degrees to verify and the gap is on only one axis. At the same time I got a new laptop so I installed the latest version of makerware. I have uninstalled and tried makerware version 3.6 and 3.7 and 3.9 without improvement.

If I turn the part 45 degrees is only happens in the corners. Did installing a new hot end and nozzle cause this??? How do I correct this error? Is there some sort of calibration I need to go through.

Try printing an x3g file that you printed previously without gaps. Print it from the SD card.

If that file now prints incorrectly, then I would tend to think it's hardware/electronics related, since obviously nothing would have changed in that x3g file.
