Don't know who needs to be told this, but you cannot have precision in a 3d printer or laser, if, your bearings are dirty. If you can hear clicks or ticks... they are dirty or broken.
Remove the seal, soak or rinse in mineral spirits / naphtha. Blow dry with compressed air, and DON'T spin until oiled. Lubricate with a QUALITY oil, and reassemble.
(the oil that came "free" with that creality printer is not quality 😉)
