-There are many reasons for unwanted movements.

Be aware of all these so-called anti z-wobble devices foundespecially those that constrain the threaded rod at the top of the printer. ​Fixating ​the top of the rod makes the rods statically indeterminate,​ basically meaning that you over constrain the system. This will not help reduce z-wobble. True anti z-wobble devices decouple x and y movement from z movement and/or take the spring movement out of the coupler by constraining the threaded rod at the bottom, ​but above the coupler.+There are many reasons for unwanted movements.
