11. X-Axis Gantry Alignment

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.

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.

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

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
