Welcome to this guide on replacing the Z-axis for Sonic Mighty 8K. The Z-axis is a critical 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 walk you through the steps to replace the Z-axis on your Sonic Mighty 8K, ensuring that your printer is operating at its best and producing high-quality prints.
