Launchd[1] com.makerbot.conveyor.daemon :getpwname ("_conveyor") failed

Question

Immediately after getting a new drive installed, and using Migration Assistant to migrate my files from a backup drive, the Console is repeating the above message every 10 seconds in Console Messages and System.log. These files are getting large!
I had to change my user name during migration, but kept my old password.
Any help or guidance would be much appreciated

Well, I have finally fixed this problem myself. My Apple Dealer installed my new drive, and my system re-installation and updates. The culprit is something called "Makerbot", which is apparently for some kind of 3-D printer (which I have never had). There was no Application or Control Panel, but a lot of other "Makerbot" folders and files were left on my Mac. The solution for me was as follows:
In Terminal (as Root):
sudo launchctl stop com.makerbot.conveyor.daemon
sudo launchctl unload /Library/LaunchDaemons/com.makerbot.conveyor.plist
sudo rm -f /Library/LaunchDaemons/com.makerbot.conveyor.plist
sudo rm -f /var/log/conveyor.log
sudo rm -rf /Library/Frameworks/MakerBot.framework
I now no longer have my System Log being banged every ten seconds, and seem to be back to normal.
