| Code / ID | Description | Probable Cause & Solution | | :--- | :--- | :--- | | | Focus Position Error | The Z-axis cannot find the focal point. The focusing lens may be loose, or the capacitance sensing is failing. Clean the lens and check the Z-axis drive. | | H210 | No Signal from Head | Communication lost between the cutting head sensor and the CNC. Check the fiber optic cable (for sensor data) or the serial connection. | | H300 | Crash / Collision | The cutting head hit the material or the slats. Check for tip damage. Recalibrate the head. | | H405 | Capacitive Sensor Drift | The height control system is drifting. Perform a "Sensor Calibration" or "Zero Set" on the head. | | Lens Temp High | Overheating Optics | Cooling water flow to the cutting head is restricted, or the lens is
The premixed resonator gas (for CO2 lasers) is running out, or there is a leak in the supply line.
Incorrect premix ratios, low helium/nitrogen/carbon dioxide supply, or a faulty gas mixer valve.
What is the appearing on your screen?
, you can access a built-in error lookup directly from the interface:
The system shuts down within minutes of turning on the resonator.
Clean the dust off the chiller condenser coils. Ensure the room temperature does not exceed the chiller's operating limits. 4. Drive & Axis Movement Errors bystronic laser error code list
| Error Code | Description | Likely Cause | Immediate Fix | | :--- | :--- | :--- | :--- | | | Assist gas pressure too high | Regulator stuck open | Tap the regulator. Cycle the solenoid valve manually. | | W-5010 | Low nitrogen pressure | Bulk tank low or vaporization rate too high | Change tank. Add vaporizer (for liquid N2). | | E-5045 | Gas mixing valve fault (O2/N2 blend) | Servo motor feedback error | Calibrate the gas mixer via software. | | E-5100 | Central pneumatic pressure < 6 bar | Shop air compressor offline | Reset shop compressor. Check main filter water trap. |
Here are the most important things to keep in mind when dealing with any Bystronic laser error:
The flow switch detects inadequate gallons-per-minute (GPM) circulating through the cutting head or resonator. Usually caused by clogged water filters, kinked hoses, or a failing pump. | Code / ID | Description | Probable

Mechanical jamming of the internal focus drive inside the head.
Bystronic machines typically display errors as numeric codes accompanied by a short text description on the ByVision interface. These codes generally fall into distinct numerical ranges pointing to specific subsystems: | | H210 | No Signal from Head
