[Sonic Mighty 12K] Replacing the Z-axis

The Z-axis is an essential component that enables the printer to move the building plate up and down, allowing for precise layering during the printing process. Over time, the Z-axis may become worn or damaged, leading to issues such as layer shifting or uneven prints. 

In this guide, we will guide you through important steps to replace the Z-axis of your Sonic Mighty 12K, ensuring that your printer is operating at its best and producing high-quality prints.
