Could a failing Inductive Proximity Sensor cause the ANYCUBIC KOBRA 2 MAX to have symptom: Sensor Failure?

This sensor is responsible for detecting the metal build plate to establish a Z-height map. Failure occurs when the internal circuitry or sensing coil degrades, preventing the probe from triggering when it nears the bed. Without this trigger, the firmware halts the process to prevent a nozzle crash, reporting a sensor failure.

Could a failing Print Head Ribbon Cable cause the ANYCUBIC KOBRA 2 MAX to have symptom: Sensor Failure?

The Kobra 2 Max operates at high accelerations which place significant mechanical stress on the hotend wiring harness. Work-hardening of the copper traces within the ribbon cable eventually leads to fatigue cracks, causing intermittent or total loss of the sensor signal to the mainboard. This break in the feedback loop is a primary cause of reported sensor errors.

Could a failing Z-Offset Calibration Module cause the ANYCUBIC KOBRA 2 MAX to have symptom: Sensor Failure?

This module, located at the rear of the print bed, contains a pressure-sensitive switch or strain gauge used to calibrate the nozzle's physical offset. If the sensor fails to register the physical touch of the nozzle during the pre-leveling sequence, the system will throw a sensor error because it cannot reconcile the proximity probe data with the physical nozzle position.
