Tightening the X and Y-Axis Belts

    When to Tighten the Belts

    If your prints are slanted or have shifting layers, it may be time to tighten both the X-axis and Y-axis belts on your MakerBot Replicator 2.

    Tightening the X-Axis Belt

    To tighten the X-axis belt, you will need the 2.5 mm hex wrench that was included with your MakerBot Replicator 2.

    1. Move the gantry to the front of your MakerBot Replicator 2.

    2. Use the 2.5 mm hex wrench to loosen the four screws on that are attached to the X-axis motor on the right side of the gantry. Do not remove the screws altogether.

    3. Pull the gantry to the middle of the MakerBot Replicator 2. Hold the motor and pull on it to create tension on the belt.

    4. While continuing to pull the gantry, use the 2.5 mm hex wrench to re-tighten the four screws on the X-axis motor.

    Tightening the Y-Axis Belt

    To tighten the Y-axis belt you will need a 5.5 mm socket wrench.

    1. Locate the Y-axis motor harness on the back right side of your MakerBot Replicator 2.
    2. Using the 5.5 mm socket wrench, loosen the two Nylock nuts located at the top and bottom of the Y-axis motor harness. Do not remove these altogether.
    3. Push down firmly on the Y-axis motor to create tension.
    4. While continuing to push the Y-axis motor down, retighten the Nylock nuts.
