During long-term operation, the Z-axis belt may loosen due to environmental factors, wear, and loosening of mechanical components. A loose belt leads to reduced transmission accuracy and step loss during operation. In more severe cases, it may cause transmission interruption. Therefore, it is particularly important to regularly check the tightness of the belt and adjust the tension in a timely manner.
