Filament Track Switch Compatible with BambuLab X2D: Eliminate Manual Filaments Re-Grouping Smart Multi-Color Routing Adapter Not for Connecting External Spool 3D Printer Accessories

["Specially designed for Bamboo X2D AMS(Include AMS 2Pro/AMS-HT unit), matching filament feed path and mounting positions. Not for P2S/P1P/P1S/X1/X1-Carbon/X1C/X1E/A1/A1 Mini/H2D/H2S/H2C","The filament track switch intelligently routes 3d printing material from your AMS units to whichever nozzle the slicer assigns, no more manual spool swapping. Dual-extrusion 3D printers significantly accelerate multi-color printing by reducing the flushing time required by single-extrusion machines","Unbinds the AMS from specific nozzles, allowing any filament to feed into any nozzle regardless of configuration. This enables dynamic filament mapping, supports mid-print color reassignments","The X2D supports up to 4 AMS 2Pro and 8 AMS-HT units simultaneously, 12 units with 24 slots in total, linked via the 4-in-1 PTFE adapter, this has nothing to do with track switch, does not reduce expansion limits. Using the 4-in-1 PTFE adapter with just two AMS units is discouraged","Widely compatible with a variety of 1.75mm filaments such as PETG, ABS, TPU and PLA, etc. It does not support materials that are sensttive to feed resistance and may fail to load or unload; it also does not support external spools. If you need to print using an external spool, you must remove filament track switch. Easy to install, learn more about installation on Wikii"]
