  1. Push the X-axis gantry forward The space between the XY Joiners and the front plates should be the same. If the space is equal on both sides, you may skip to the next chapter.
    • Push the X-axis gantry forward

    • The space between the XY Joiners and the front plates should be the same.

    • If the space is equal on both sides, you may skip to the next chapter.

    • If the space isn't equal and the gantry doesn't sit flush with the front, please follow the next steps.

    • The bed plate is hidden in this chapter for ease of understanding, there is no need to remove it.

  2. Loosen the Y-rail carriage screws slightly Adjust the belt tensioning screws in order to equalize the gap on both sides If you loosen the belt tensioning screw, the gantry will move forward, closing the gap
    • Loosen the Y-rail carriage screws slightly

    • Adjust the belt tensioning screws in order to equalize the gap on both sides

    • If you loosen the belt tensioning screw, the gantry will move forward, closing the gap

    • If you tighten the belt tensioning screw, the gantry will move back, enlarging the gap

    • Adjust both belt tensioning screws until the gap is equal on both sides and the gantry sits flush on the front plates

    • Squeeze the XY-Joiner against the front plate to feel if there is any play. While squeezing there shouldn't be any play, keep adjusting the belt tensioning screws until there is no gap on either side.

  3. Tighten the carriage screws Loosen the screws on one of the Y-axis linear rails slightly Align the Y-axis linear rails from the front to the back:
    • Tighten the carriage screws

    • Loosen the screws on one of the Y-axis linear rails slightly

    • Align the Y-axis linear rails from the front to the back:

    • Little by little move the gantry backwards

    • Tighten the screw on the rail closest to the carriage as you move it

    • Repeat for all screws along the rail

  4. Test the movement of the Y-axis over the full travel distance
    • Test the movement of the Y-axis over the full travel distance

    • Small changes in resistance are normal, but becoming much harder to push, or binding completely are not

    • If the gantry is hard to push, or it binds completely, repeat Step 3 for the other Y-rail
