Dual Guard Sensor

Dual Guard Filament Exhausted or Stuck Sensor for 3D Printer

The Dual Function Filament Sensor (Dual Guard Sensor) is the ultimate accessory for your 3D printer. It is designed to pause your printer in the event of filament running out or stuck (overlapping) in your spool (for spool on top of Z axis only). The operating principle is very simple thanks to the use of a mechanical endstop and neodymium magnets.

Compatibility: The "Pin 27 Board" card is necessary for the original cards Ender3, Ender3_PRO, Cr10, etc... (Card with ATmega 1284p, Creality 1.1.4, 1.1.5, etc.). It allows you to release pin 27 in order to connect the sensor. For 4.2.2 and 4.2.7 Creality boards, the PIN27BOARD board is not required. Simply connect the sensor to the dedicated pin.

Main features:

• Pauses printing if filament runs out or is stuck
• Simple operating principle with mechanical endstop and neodymium magnets
• Compatible with various 3D printer original boards
