Description

  • The Anycubic SP Kobra S1 / S1 Combo Material Break Detection PCBA: is the dedicated optical runout and filament detection sensor module designed for the enclosed Kobra S1 series.Positioned along the main filament input path, this sensor board monitors real-time filament presence and movement. If a spool runs out or a break occurs mid-print, it immediately alerts the mainboard to pause the print job cleanly—preventing ghost printing and head damage.
  • High-Sensitivity Photoelectric Sensing: Uses an infrared optical interrupter to detect filament presence without placing mechanical drag or resistance on the feeding filament.
  • Auto-Pause & Resume Support: Instantly triggers an automatic firmware pause whenever filament is depleted or broken, saving the print state for seamless resuming after a spool reload.
  • Compact Low-Profile Design: Engineered to mount flush inside the Kobra S1 entry housing without interfering with PTFE tube routing or internal chamber motion.
  • Direct Plug-and-Play Assembly: Comes pre-soldered with a high-flex lead harness and micro JST header for quick connection to the main motherboard or distribution PCB.

Technical Specifications

  • Compatible Models: Anycubic Kobra S1 / Kobra S1 Combo
  • Sensor Type: Infrared Photoelectric (Optical) Break Detection
  • Operating Voltage: 3.3V / 5V DC
  • Supported Filament Diameter: 1.75 mm

Maintenance & Care Tips

  • Keep Optical Pathway Free of Dust: Fine filament dust or plastic strings can obstruct the infrared beam path. Blow compressed air through the sensor slot periodically to prevent false "Out of Filament" errors.
  • Check PTFE Tube Alignment: Ensure the entry and exit PTFE guide tubes seat flush against the sensor channel so raw filament feeds straight through without snagging on the PCB edge.
  • Verify Signal LED Status: Most Kobra S1 detection boards feature an onboard indicator LED. Verify that the light turns ON when filament is inserted and turns OFF when pulled out to confirm proper sensor operation.
