We a had a print job that got stuck and was unattended. During the print job the extruder must have become jammed or stuck and the filament kept feeding over the print head and hardened. Has anyone ever experienced this? Our biggest worry is the wire that is unprotected leading to the print head may have been damaged. Does anyone have any ideas of how to get the hardened plastic off of the print head without damaging the print head. We had the thought of heating it up by it is so far up and over the print head it won't heat that far up to melt it.
We are using a MakerBot Replicator 2. Thanks in advance for any help you can provide.
