Then, few prints and your perfect presure over the filament gets modified by this vibration. This guide removes all the problem.

Instructions

1. Print (I used 0.4 mm nozzle, 0.3 mm layer, 60% fill)
2. Screw the original screw, the hole is tight so I used a bit of 3-in-1 oil to make the screw thread
3. Insert the piece and screw into near the original nut (keep the nut near this guide)
4. Adjust the filament pressure now, it will be rock solid :)
5. Enjoy!
