Description
The Z Belt Timing Pulley is located on the bottom side of the printer, and used to connect the Z axis leadscrew to the belt of the printer. It transfers drive from the belt to the leadscrew, so a worn pulley causes skipped teeth, inconsistent layer heights, and a bed that drifts out of level.
Features:
Connects Belt to Leadscrew: Transfers drive from the Z belt to the Z-axis leadscrew for accurate vertical positioning.
Cover and Screw Included: Ships with the pulley cover and its M3x6 mounting screw.
Plastic and Copper Construction: Wear-resistant build for smooth running and long service life.
Underside Installation: Accessed from the bottom of the printer, following the guide on the Bambu Lab Wiki.
When to Replace: Worn or rounded pulley teeth, clicking or skipping during Z moves, inconsistent layer heights, or a bed that keeps drifting out of level.
