Overview: Upgrade your 3D printing setup with a reliable auto-refill BMCU module designed for AMS/MMU filament systems. Equipped with a Hall sensor and bidirectional buffering, this module improves filament handling, reduces jams, and delivers smoother multi-filament printing.

Specifications:

• Item Type: BMCU Auto Refill Module
• Compatibility: AMS/MMU filament hub systems; compatible with A-series and P-series mini 3D printers
• Sensor Type: Hall sensor for accurate filament detection
• Function: Auto refill, bidirectional buffering, filament monitoring and feeding
• Connector: 4-pin (4P) anti-reverse cable
• Installation Notes: Do not hot-plug. Always power off the printer before connecting or disconnecting the module to prevent damage.
• Important: Disable the long retraction option when using the filament cut feature to avoid damaging the filament hub or BMCU.
• Warning: Before turning off the printer, ensure no filament is loaded into the tool head. If a filament position error occurs on startup, unplug the PTFE tube from the BMCU, manually operate the cutter lever on the tool head to cut and release the filament, pull the filament back from the BMCU, then reinsert the tube.
