Bambu Lab AMS Hub The AMS Hub is used to expand the number of AMS connected to Bambu X1 series printers from 1 (4 channels) to a maximum of 4 (16 channels) to improve the refueling speed across your multiple AMS units and support the redundancy of a buffered signal. Expand Your AMS Options The built-in buffer of the printer can only be connected to 1 AMS. When replaced with AMS Hub, the printer will be able to connect up to 4 AMS. Installation Install the AMS Hub on the back of the printer, replacing the Filament buffer if you have one, and use the matching Bambu 4 Pin cable to connect to the printer, use the Bambu 6 Pin cable to connect to the first AMS, then continue to use the 6-pin cable to connect the remaining AMS in series. Use the matching PTFE Tube to connect the AMS Hub and the air tube connector on the back of the printer, the tube should pass between the 4-pin plug and the spool holder to reduce the resistance. According to the placement of the AMS and the printer, you can choose the appropriate length of the PTFE tube to connect the AMS and the AMS Hub. The tube should be as short as possible and avoid winding to reduce the feeding resistance.
