This timing belt kit includes replacement belts for both the X and Y axes on the Anycubic Kobra 2 Pro. Timing belts are a wear item — over hundreds of hours of printing, they stretch, lose tension, and develop wear on the tooth surfaces. This gradual degradation causes dimensional inaccuracy, layer shifting, ringing artifacts, and inconsistent positioning that worsens over time.

Replacing worn belts restores precise motion control and brings print quality back to factory-fresh levels.

When to Replace

Visible wear, fraying, or cracking on the belt teeth or backing, layer shifting that isn’t caused by loose pulleys or stepper issues, ringing or ghosting artifacts on print surfaces despite correct acceleration settings, belt tension that won’t hold after re-tensioning, and as part of preventative maintenance after extended use.

What’s Included

Timing belt × 1 (X axis)
Timing belt × 1 (Y axis)

Compatibility

This belt kit is designed for the Anycubic Kobra 2 Pro. It is not compatible with the Kobra 2, Kobra 2 Max, Kobra 3, or Kobra S1 — those models use different belt lengths and configurations.

Installation

Power off the printer. Release the existing belt tension, remove the old belts, route the new belts along the same path, and re-tension. Ensure the belt teeth are properly seated on the pulleys and idlers with no twisting. Tension should be firm but not overtight — the belt should deflect slightly when pressed but not feel loose.
