AI LiDAR Communication Anomaly
Error E2001 indicates a handshake failure between the toolhead toolboard and the AI LiDAR optical triangulation module, preventing automated first-layer surface calibration.
Strain Gauge Zero-Point Drift
Key 2505 trips when the Klippy/MCU host detects that the analog baseline voltage from the bed-mounted strain gauge load cells has drifted outside the allowable tare window (typically > +/- 150mV off nominal baseline) prior to auto-bed leveling or homing sequences.
Toolhead CAN Bus Communication Failure
Error Key: 2565 indicates a loss or degradation of CAN bus differential data packets between the mainboard and the toolhead breakout MCU (typically STM32/GD32). Klipper firmware halts operations to prevent thermal runaway and positional desynchronization.
Bed Strain Gauge Sensor Anomaly
Error key 2564 trips when the Klipper-based MCU detects that the analog-to-digital converter (HX711/ADC) on the bed leveling strain gauge sensor board returns an out-of-range baseline voltage, excessive drift, or fails to detect an expected trigger threshold during the auto-bed leveling or homing routine.
AI LiDAR Calibration Communication Anomaly
The toolhead controller board has lost communication or failed the initial handshake protocol with the AI LiDAR sensor module during bed leveling calibration or first-layer scanning routines.
