Spring load Y axis, anet A8, Prusa I3

thingiverse

I've heard about the benefits of a spring-loaded axis for CNC machines, which inspired me to create my own version for my 3D printer. This modification aims to reduce belt vibration and maintain even tension at all times. The standard bed level spring (7mm) I initially used proved insufficient due to my heavy bed's weight. To compensate, I added an extra pen spring, which significantly improved the stability of the system. If you have a similarly heavy bed or plan to upgrade your 3D printer in the future, I highly recommend using a more powerful spring. To secure the springs, I employed a long M3 screw (52mm) and its corresponding nut, ensuring a robust and reliable setup that effectively dampens belt vibrations.
