How To Unclog A MakerBot Replicator 2 Nozzle

From time to time the MakerBot Replicator 2 3D printer nozzle will clog, leading to air-printing, jamming, and printer downtime. Replacing it with a fresh nozzle will fix the issue, but if you don’t have time to wait for a part, try manually unclogging it first.

Tools Needed:

  • Side or flush cutter

Let’s Get Started

  1. Preheat your Replicator 2 to 230°C (which should be the factory setting).
  2. Once the printer is preheated, grab the filament with your left hand and push down on the black drive gear block with your right hand.
  3. Push down on the filament until you see plastic melting out of the nozzle.
  4. Pull up quickly on the filament to release it from the machine. This should grab the clog.
  5. Use the side cutter to clip off the end of the filament that contains the clog.
  6. Repeat this process 3 to 5 times.
  7. Print a 10 to 15 minute test print to make sure your printer is working properly.

Still clogged?

  1. If this does not solve the issue – go to “Info and Settings” on your MakerBot Replicator 2.
  2. Then select “Preheat Settings”.
  3. Change the temperature to 250°C.
  4. Repeat the same steps that you did at 230°C.
  5. Repeat the push down, pull up process 3 to 5 times.
  6. If the nozzle is clear return to “Info and Settings” then “Preheat Settings”.
  7. Change the temperature back to 230°C.
  8. Print a 10 to 15 minute test print to make sure your printer is working properly.

Still clogged?

  1. If this does not solve the issue – go to “Info and Settings” on your MakerBot Replicator 2.
  2. Then select “Preheat Settings”.
  3. Change the temperature to 260°C. DO NOT EXCEED THIS TEMPERATURE AS THIS COULD CAUSE DAMAGE.
  4. Repeat the push down, pull up process another 3 to 5 times.
  5. If the nozzle is clear return to “Info and Settings” then “Preheat Settings”.
  6. Change the temperature back to 230°C.
  7. Print a 10 to 15 minute test print to make sure your printer is working properly.

Still clogged?

If this does not solve your clog issue, either purchase a replacement nozzle or contact us to walk you through how to fix your nozzle.
