The Bambu Lab Filament Track Switch is a game-changing accessory for Bambu Lab X2D, Bambu X2D Combo, and Bambu Lab H2C printers. Designed to work seamlessly with your existing Bambu Lab filament setup, this intelligent automatic filament switcher dynamically routes any filament from your AMS units to the correct nozzle, hotend (or hot end), extruder, and print head — without manual spool swapping. Whether you're using a standard build plate or other Bambu Lab accessories, the switch integrates smoothly without reducing the printer's native AMS expansion capacity (up to 12 AMS units). It delivers true dynamic filament mapping for dual extruder 3D printers, making it an ideal multi-color 3D printer filament switcher for complex prints. Please note current limitations: external spools are not supported; sensitive filaments (PLA-CF, PLA Glow, PLA Silk) may require adjustment; high-precision nozzle offset calibration is temporarily unavailable (firmware update pending). For H2C users, same restrictions apply. Perfect for multi-material printing on Bambu Lab systems — eliminate manual filament regrouping and boost your printing efficiency.

• 【Eliminate Manual Filament Re-grouping for X2D & H2C】The Filament Track Switch intelligently routes any filament from your AMS units to whichever nozzle the slicer assigns. No more manual spool swapping — perfect for users of Bambu Lab X2D, Bambu X2D Combo, and Bambu Lab H2C printers.
• 【Dynamic Mapping for Peak Efficiency – Automatic Filament Switcher】Unbinds AMS from specific nozzles, allowing any filament to feed into any nozzle, hotend, extruder, and print head. Supports mid-print color reassignments, boosting multi-color efficiency. This dynamic filament mapping for dual extruder 3D printer feature makes it a true multi-color 3D printer filament switcher. (Note: Not compatible with external spool.)
• 【 Massive AMS Expansion – Works with Your X2D Build Plate & Accessories】When installed on Bambu Lab X2D, the printer supports up to 4 AMS 2 Pro + 8 AMS HT units (24 slots). The switch does not reduce expansion limits, and works seamlessly with your existing Bambu Lab X2D build plate and other Bambu Lab X2D accessories
• 【Important Usage Restrictions for X2D & H2C Users】 1.Avoid using 4-in-1 adapter with only 2 AMS units. 2.Sensitive filaments (PLA-CF, PLA Glow, PLA Silk) may fail — try moving to another AMS slot. 3.External spool not supported; remove the switch to use external spool
• 【Current Calibration Limitation (Firmware Update Pending)】After installing the switch on Bambu Lab X2D or H2C, high-precision nozzle offset calibration cannot be performed. To run calibration, remove the switch and restore the original setup. A future firmware update will resolve this
