What is BMCU

BMCU is the next-generation project following AMCU. It is a third-party open-source automatic material switching system compatible with AMS lite. BMCU is compact, low-cost, and fully open-source. 🛠️

Its stability is not as high as AMS lite, and as a third-party accessory, it may become unusable due to future official firmware updates. ⚠️

The following description comes from the BMCU project on Lichuang Open Source Hardware Platform (OSHWHub)

BMCU is designed based on open-source materials. Referring to the protocol information of bambubus on GitHub and community-provided reference data, we created a system that simulates the behavior of AMS, applicable to the A-series printers. BMCU is a specialized evolution of AMCU, and many of its design concepts are based on publicly available information about the working principles of AMS lite.

Due to its reliance on open-source content and its high functional similarity to AMS lite, BMCU is open-source but not allowed for commercial use. It is strictly for personal DIY and educational purposes.
