The Anycubic Kobra 3 Series / Kobra 3 Max Print Head Connection Cable (Extruder Signal Harness) is the main cable that transmits power, sensor data, stepper motor control signals, and heater telemetry between the printer's mainboard and the moving print head.

Features:

• Highly flexible cable: Encased in a durable, protective silicone sheath, designed to withstand millions of motion cycles without copper conductor fatigue during high-acceleration 3D printing (20,000 mm/s).
• Industrial high-flex wiring: Numerous copper conductors specially designed for continuous movement along the X and Z axes without developing internal cracks.
• Integrated angled connector: Features a reinforced angled connector that securely locks onto the top of the print head board, preventing contact disruption during rapid direction changes.
• Unified power and data transmission: Includes high-quality lines for the 300°C heater, combined with signal cables for print head thermistors, auto-leveling sensors, and cooling fans.
• Durable outer jacket: Covered with an orange silicone/braided tube, resistant to heat, frame impacts, and wear from friction with PTFE tubes.
