| Error Code | Description | Likely Cause | Immediate Fix | | :--- | :--- | :--- | :--- | | | X-axis following error | Dirt on linear guides; excessive acceleration | Clean rack/pinion. Reduce cutting speed. | | E-2028 | Y-axis limit switch triggered | Overtravel or faulty proximity sensor | Manual jog away from limit. Check sensor wiring. | | W-2050 | Reference point lost | Battery voltage low on absolute encoder | Replace CNC backup battery. Remachine reference marks. | | E-2101 | Z-axis collision detected | Cutting head hit a raised slug or fixture | Power off. Manually retract Z-axis. Check nozzle for damage. | | E-2200 | Servo drive fault (HW) | Axis stalled. Brake not releasing. | Check 24V power supply to drive. Reset drive breaker. |
Often caused by a dirty cutting head. Clean the ceramics and nozzle holder with alcohol. "Drives Not Ready" Drive Failure bystronic laser error code list
| Error Code | Message / Meaning | Common Cause & Fix | | :--- | :--- | :--- | | | Resonator pressure too low | Refill laser gas mixture or check pressure sensor. | | E-1215 | Laser pulse not fired | Check firing signal, high-voltage supply, or PSU. | | E-2103 | X-axis following error | Mechanical binding, bad encoder, or servo drive fault. | | E-2208 | Z-axis soft limit reached | Incorrect zero point; recalibrate cutting head. | | E-3125 | Collision detected on cutting head | Nozzle hit workpiece or sheet; re-teach head position. | | E-4022 | Capacitive sensor out of range | Dirty nozzle tip, damaged sensor cable, or wrong standoff. | | E-4510 | Lens temperature too high | Cooling water flow low; clean chiller filter or refill coolant. | | E-5120 | Assist gas pressure too low | Check tank level, regulator, or solenoid valve. | | E-6102 | Cooling water flow interrupted | Pump failure, air in system, or blocked hose. | | E-7801 | ByVision communication timeout | Restart HMI; check Ethernet cable or IPC. | | Error Code | Description | Likely Cause
