Setting Up a New Smart Extruder+

    Why to Calibrate

    Every MakerBot Smart Extruder+ and 3D printer we send out is tested in our factory, but there may be small variations between individual 3D printers and extruders. If you are connecting a new extruder to your MakerBot Replicator+ for the first time, you will need to perform some calibration steps to compensate for any differences.

    You should follow these steps before printing whenever you install an extruder for the first time. Once your extruder is set up for a specific MakerBot 3D printer, you can attach and detach it as many times as you like without going through this process again.

    1. Install the extruder

    Locate and unwrap the Smart Extruder+ and press it against the back of the extruder carriage, with the connector pins facing the front of the MakerBot Replicator+. Magnets will lock the extruder into place. For more information about installation, click here.

    2. Update Firmware

    It's important to always keep your MakerBot 3D printer's firmware up to date. Firmware updates often include improvements to Z-axis homing, and your extruder may not home correctly if you don't have the newest version.

    3. Start a Print

    Monitor the first layer of your print carefully. If the extruder nozzle scrapes against the build plate, or if you receive a homing error, the extruder is too close to the plate. If the plastic coming out of the extruder doesn't adhere well to the build plate, the extruder is too far from the plate. In either case, you can recalibrate the Z-axis offset or manually adjust the Z-axis offset to correct the starting height of the build plate.
