Hi All, unfortunately I already bought some original S5 X-slinding blocks including the belts before I found this topic here. The old, worn out sliding block parts are black, the new ones are white, maybe those are different in material. Is there any describtion available how to exchange the blocks in the best/correct and most simple way? BTW: indeed I lost printing quality over time after this rod-got-loose-in-block-casing-seat problem occured. (my S5 sliding block problem started by a collision of printing head with the glas bed...) I firstly though about some z-wobbeling issues but most likely my printing problems seem to result mainly from displacements due to X-rod play while printing.
