Description
The Core XY Movement System is the complete motion assembly that drives the toolhead across the X and Y axes. It is supplied as a full pre-assembled unit — rods, belts, pulleys, and carriages together — so a damaged or worn motion system can be restored in one replacement instead of sourcing and fitting individual parts.
The P1 series uses the proven CoreXY kinematics of the Bambu Lab flagship printers, reaching 500 mm/s print speeds with up to 20,000 mm/s² acceleration. Keeping that motion system in good condition is what preserves print accuracy at those speeds.
Features:
Complete Motion Assembly: Supplied as a full pre-assembled unit rather than separate components.
Restores Print Accuracy: Replacing a worn or damaged motion system eliminates ringing, layer shifts, and dimensional errors that persist after belt tensioning.
Pre-Assembled and Aligned: Comes assembled from the factory, removing the alignment work required when rebuilding from individual parts.
Genuine Bambu Lab Part: Original replacement motion system for the P1 series.
When to Replace: Crash damage to the gantry, bent rods, persistent ringing or layer shifts after belt re-tensioning, or rough and notchy toolhead travel.
Advanced Installation: A major teardown involving the full gantry. Follow the XY Axis Assembly replacement guide on the Bambu Lab Wiki carefully.
