The function of the Z belt is to transmit the motion of the Z motor to the three Z-axis lead screws.
**IMPORTANT TO KNOW**
1. The label on the Z belt you received may label as "XY belt" due to improper production operation, the actual product is the Z belt you ordered, which will not affect its functionality.
2. We apologize for any confusion this may have caused. Rest assured, we are taking immediate corrective actions to address this issue. Thank you for your understanding.
