Rather than being just a ramen-esque tangle, this fail taught me a little something about MakerBot Replicator maintenance.
The print failed the same way every time. It would get to about 45%, and then stop extruding filament. My best guess is that my HBP and nozzles aren’t quite level– the Replicator’s been taking a beating over the last couple of weeks with all the nozzle changes and such, and I haven’t leveled the platform in a while.
So once the model built up to a certain point, the nozzle would bang into the extruded plastic, get a clogged tip, and then fungus fail.
