AMS Feeder Unit (Hall)

This part is also known as AMS First Stage Feeder.

The AMS Feeder Unit (Hall) is specially designed to support the AMS for printing multiple colors and materials.

Each AMS has 4 feeder units, and each feeder unit has its own motor and gears to actively push the filament forward or wind it back to the spool.

The feeder unit has a sensor to detect filament. When a filament is inserted, the feeder unit will pull the filament automatically. When a filament needs to be winded back, the feeder unit will drive the AMS driving sleeve to rotate the spool for filament winding.
