After installing this shuttle, it started getting first layer inconsistency corner to corners with IGUS Chainflex 113 that is not super flexible like other cables like 3DO i believe. The toolhead shaking easily and not snug fits into the shuttle due low strength magnets and bushing with larger hole. This is quality issue and seems LDO not tested this batch properly. Contacted West3D. waiting for their help.
Here is a comparison between Aliexpress cheap bushing vs LDO branded bushing. I am disappointed now as my printer is broken again and I need to wait for longer time or revert to the printed Shuttle again.
