CREALITY ENDER 3 V3 Failed

CR-Touch Auto Leveling Sensor Kit

The CR-Touch uses a hall-effect sensor to detect the bed surface. Mechanical failure occurs when the internal pin becomes bent or the electromagnetic solenoid fails to deploy the probe, preventing the printer from establishing a homing coordinate and resulting in a leveling sequence abort.

Z-Axis Strain Gauge Sensor Board

This specific PCBA contains the load cell circuitry that detects the physical resistance when the nozzle touches the build plate. Micro-fractures in the strain gauge or faulty communication on this board cause the 'Key 2401' error, as the system cannot verify the Z-axis pressure required to set the initial Z-offset.

Toolhead Breakout PCBA

The breakout board acts as the signal aggregator for the extruder, CR-Touch, and X-limit switch. Failure in the communication bus on this board—often due to thermal cycling or vibration-induced solder fatigue—leads to 'Key 3000' unknown errors where the main motherboard loses the data stream from the leveling sensors.
