Compatibility: Specifically designed for Bambu P1S, P1P, X1, and X1C models. This AMS Hub allows you to connect up to 4 AMS units to your printer, expanding the capability from 4 to 16 channels. Increased Efficiency: By expanding to multiple AMS units, you enhance the refueling speed and support redundancy, ensuring smoother and more reliable printing operations. Easy Installation: Mount the AMS Hub at the printer's rear, replacing any existing filament buffer. Connect it to the printer using the provided Bambu 4-pin cable and link AMS units sequentially with the 6-pin cables. Ensure the PTFE Tube is routed efficiently to minimize feeding resistance. Optimal Setup: Choose the appropriate PTFE tube length based on the AMS and printer placement to avoid unnecessary winding and reduce resistance further.
