SENTINEL is a 3D printer filament detector and cleaner.
Never miss a 3D print again because of an empty spool or dust on the filament. SENTINEL is your ultimate filament watchdog.
More than a few user came back to a 3d print job completed but an unfinished object due to lack of raw materials. With SENTINEL, the days of prints failed due to a lack of filament or dust on the filament are over. SENTINEL detect your filament and pause your print.

The Filament Sentinel is available for either 1.75mm diameter or for 2.85mm diameter filaments.
It works with all available materials; flexible, clear, opaque, filled, etc.
The Filament Sentinel can handle as many filaments simultaneously. As soon as one of them will be missing, the Sentinel will send a message to the next one, up to your main board.

The Filament Sentinel is well integrated within firmware and a pause routine is engaged once there are no more filaments in your printer.
