I'm Getting a Heating Error

If you’re seeing Error 55, 57 or 58, the temperature of the Smart Extruder+/Smart Extruder has changed unexpectedly. If you’re seeing Error 57, the temperature has dropped. If you’re seeing Error 58, the temperature has risen.

There may be an issue with the connection between the extruder and the extruder carriage or with the internal heating components of the extruder.

Does your MakerBot Replicator recognize that an extruder is attached?
