I am also having major layer shifting in the X axis on our BIG60 V3 where I work. I doubt changing the ceramic bearings would change much since the bearings move parallel to the axis if anything maybe the bearing on the Y axis would be a problem for layer shifting in the X axis. I think the motor gear slipping could be a reason, if not, tension in the belts, but its such a pain to access the components. TwoFiftySWB what kind of upgraded parts did you receive from Modix? theres another thread on reddit but no clear solution the neither.
