Filament Run-out Sensor:

The Filament Run-Out Sensor is designed for those who are looking to print intensively jobs and large object prints, fearlessly.

Eliminate the risk of unfinished prints and the waste of half-used filament spools. The Filament Run-Out Sensor monitors your filament and prevents unfinished prints and “air printing”.

For large volume prints that require multiple spools or for specialty filament options prone to breakage, the sensor will automatically detect when material has run out and will pause your project until you to return. Combined with Raise3D print recovery for power outages, this add-on ensures continuous production with your N-Series system.

The Filament Run-Out Sensor detects filaments by using high quality optical sensors compatible with: opaque, translucent, and transparent filaments. This optical sensor maintains constancy and tension without the interference of physical gears or grips, allowing compatibility with multiple material types including flexible filaments. (For translucent/transparent/flexible materials, only Raise3D Branded filament is verified.)

Thermal Protector (free, on request):

In the unlikely event of damage in the extruder board cable, the thermal protector is a safeguard to prevent an unmonitored increase in extruder temperature. The installation of the included thermal protector is recommended especially for users who operate the N-series 3D Printers exhaustively.
