Anycubic Chiron Z-axis top bearing support

thingiverse

Anycubic Chiron Z-axis screw rod vibrates during printing specially when there is sudden change in direction. This vibration causes a rattling noise by the Z-axis screw rod. I do not know if the bearing housing was intended to be not holding the Z-axis top bearing to stay in one place but one thing for sure Anycubic3d customer support did confirmed that it should not be like that. https://youtu.be/pkfqIoRITeY One temporary solution is to raise the Z-axis rod a littler higher that it touches the plastic cover pressing the rod under pressure avoiding rattling motion. However, over time with several printing sessions the rod will start to move back and forth again so a permanent solution is required. Removal of the top plastic cover and the bearing is required that you can put the printed plastic in place. https://youtu.be/pUSsymEn9zg This tiny plastic model is a simple and working solution which does not require any modification on the printer, only an add-on part. This printed plastic simply supports the bearing itself that holds the rod that it will stay in one place. Maybe the best material for this is a flexible filament, the one that is more stiff but still have that rubber like characteristic that absorbs vibration while not allowing rattling sound. However, the time of making this project, what I have on the printer is ABS. ABS still have some softness or absorbing characteristic than using a harder kind of plastic. Those that have access to rubber material, you can simply cut a piece of rubber similar to the shape instead of printing one. This solution is done utilizing the 3D printer at hand in the spirit of having a 3D printer to create practical solutions that is repeatable and useful and whoever having the same problem can also apply the same solution easily.
