If you hear strange squeaking noises coming from the Z-axis, even though you already lubricated it, it's time to realign the Z-axis. It doesn't happen so often, but it can happen over time. Follow the next steps to realign the Z-axis:

1. Go to Utilities/Maintenance/Move printing platform and move the printing platform to its middle position.

2. Take out the central bottom cover

3. Partially loosen the clamps that hold the Z-axis sidebars, both upper and lower clamps, and the screws that hold the Z motor.

4. Partially loosen the nuts that hold the clamps, you'll see they admit some horizontal movement.

5. From the Move printing platform menu (Utilities/Maintenance/Move printing platform), lower the platform to its bottom position. Once in the bottom, move it back up all the way to the top

6. Repeat the previous step a couple of times to align the Z-axis.

Conclusions

To reassemble again the axis, follow the previous steps from step 4 and in reverse order.
