Problem description: Elegoo Saturn 2 8k will make a creaking noise when printing. But the most important thing is that when printing, the stripes appear at the same height on all layers.
Solution: If there is noise during the movement of the z-axis, we recommend readjusting the structure and then leveling. Loosen these screws, reinstall them, and grease the z-axis screws and sliders. (Conventional grease or lubricating oil can be used if there is no special requirement for lubricating grease).
Note: Make sure that the support part is horizontal and not inclined.
