Changing Filament

    How to Change Filament

    The easiest way to change your filament on your MakerBot Replicator 2 is to use the LCD panel.

    1. On the LCD panel, select  Utilities > Change Filament > Unload.
    2. Wait for the extruder to heat to the set temperature.
    3. Push down on the extruder arm and continue to hold it down as you gently pull the filament out of the extruder. Then release the extruder arm. If the extruder on your MakerBot Replicator 2 does not have an extruder arm, just pull the filament free of the extruder.
    4. Remove the old spool and replace it with the new spool.
    5. Feed the MakerBot PLA Filament through the filament guide tube.
    6. Go to the LCD panel and select Utilities > Change Filament > Load. The MakerBot Replicator 2 will start to heat your extruder.
    7. When the extruder is heated, the LCD panel will prompt you to load the filament into the extruder. Click through the message until your MakerBot Replicator 2 asks you to press the M when you see plastic extruding.
    8. If your extruder has a lever arm at the side, push it down and hold it in place. If you have an extruder without an arm at the side, continue to the next step.
    9. Insert the free end of the filament into the hole in the top of the extruder.
    10. Push the filament down until you feel the motor pulling it in. Wait until you see plastic start to emerge from the extruder nozzle. If your extruder has an extruder arm, release it. Watch to make sure plastic is still extruding from the nozzle. Then press the M button to stop extrusion.
      Note: If you're changing colors, you'll need to run the extruder for a few moments to clear out the old color before stopping extrusion. If you're changing materials, it can take even longer -- make sure that all the old material is extruded before you start a new print.
    11. Push the guide tube back into the opening on the top of the extruder.

    Changing Filament During a Print

    You can change filament during the print process to create a print with layered colors. Press the left arrow button to get to the Active Build menu, then select Change Filament. The extruder will move away from your print. Select Unload, then replace the spool and filament as you did in the steps above. After you change the filament, select the left arrow button to return to the Active Build menu. Select the entry for Resume Print.

    Using MakerBot Desktop

    *The MakerBot Print software will be unable to detect this model via USB cable. Only MakerBot Desktop Software can be used for this function.

    You can also load and unload filament using MakerBot Desktop.

    1. Connect your MakerBot Replicator 2 to your computer using the USB cable that came with your MakerBot Replicator 2.
    2. In MakerBot Desktop, open the print monitor panel and select Change > Unload.
    3. Wait for the extruder to heat. When the extruder is fully heated, you'll hear a sound and MakerBot Desktop will display an image indicating that you can now unload the filament.
    4. Remove the old spool and replace it with the new spool.
    5. In the print monitor panel, select Change > Load. Wait for the extruder to heat before loading the filament.
    6. Push the filament into the extruder's loading tube until you can feel the motor pulling the filament in. When you see plastic emerging from the extruder nozzle, click Done.
    Note: If you're changing colors, you'll need to run the extruder for a few moments to clear out the old color before clicking Done. If you're changing materials, it can take even longer -- make sure that all the old material is extruded before you start a new print.
