What is the BMCU-370?

The BMCU-370 is a multi-color feeder for up to four filaments. Unlike many other systems, BIQU relies on a powerful370 motor with Hall sensor. This provides more torque, quieter operation, and more precise filament detection compared to smaller standard motors.

Highlights at a glance:

  • Plug & Play for Bambu:It emulates the AMS Lite and works directly with printers like the A1, A1 Mini, or the P1 series.

  • Open-Source Power:The system is based on the 'Bambubus' protocol. For those who enjoy tinkering, this is a playground for custom firmware adjustments.

  • Robust Design:The bidirectional buffering allows for smoother filament feeding, reducing material wear and clogs.

The Klipper Factor: Is freedom coming for everyone?

Especially exciting for the community: BIQU plans integration intoKlipper. This means that this system will no longer be limited to the Bambu world in the near future. Anyone who owns a Voron or a modified Ender with Klipper could obtain a cost-effective and powerful multi-material solution with the BMCU-370.

Conclusion

The BIQU BMCU-370 is more than just a "cheap clone." It is a statement for open hardware. Currently priced under €60-80 (depending on the kit version), it offers performance that is on par with the original – and with the upcoming Klipper support, it will become truly interesting.
