The openbuild control did a auto update and now my Z axes is jerking up and down . I tried to invert in the settings but nothing worked. I also had to reset the X&Y axes
Very very unlikely to be update related. Jerky movement is almost always wiring: if only 3 of the 4 stepper motor wires are making good contact it shakes like that. Recheck your wiring, its been a while, some terminal maybe rattled loose, pulled out, or broke off (sometimes inside from continuous bending)
