Overview
The Toaiot BMCU 370C buffering module is a drop-in upgrade for Bambu Lab A1, A1 mini and P1 series printers running an AMS or MMU multi-material setup. It keeps filament tension smooth and consistent while the AMS auto-refill system switches spools, so your prints keep running without manual intervention.
Built around a Hall sensor and a offerirectional buffering design, the unit detects filament movement in real time and feeds it back to the printer with precision. The result is fewer jams, fewer failed swaps and cleaner layer transitions on long multi-color prints.
Whether you are a hobbyist pushing multi-color prints or a maker running production batches, this module helps your AMS work the way it was meant to.
