Smart Extruder + Explosion now it is encased in filament

This extruder is only a couple months old. Thankfully I have a backup extruder. Do you think Makerbot will replace it?

Makerbot most likely will not replace. They however will sell you another.

I would heat up the hot end as if I was going to print and remove the largest globs, using side cutters and needle nose pliers.
After the majority is removed then depending on what filament you were printing would determine how I would proceed in cleaning the remaining filament

If ABS I would use a jar or acetone and de-solve the remaining filament.
If PLA I would slowly heat and scrape the filament from the parts until I had the more expensive retrievable parts.

Then determine if it was worth my time to spend on the cheaper parts if not then throw the cheaper consumables away, and replace with new.

Consumables
Thermister
Hot-End Heater
Nozzle
Hot-End Heater Block

what happens? how can it block? you can ask makerbot for help.

'ask makerbot for help '
Now that's funny :-)

heat and remove, should come off easily enough.

But for it to do that - it must have come out somewhere other than the nozzle.
So you might need a new extruder.

I had the exact same problem in November, too. I am having trouble finding a vendor for the Smart Extruder +. Have you had any success?

Do you know where I can find replacement pieces for the Hot End and pices mentioned? Mine is the Smart Extruder +

Were you able to find replacement parts? I have problems too. I need Hot end parts for the Smart Extruder +
