Bystronic Laser Error Code List Hot! -
: Manually close the mirror cover and adjust the mirror position if it has shifted. 700850 – Reset! Then Make Shooting
Describe the your laser is showing (like poor edge quality or axis shaking) if the HMI is not throwing a clear error code.
: Clean the cutting nozzle holder with alcohol, exchange ceramic parts, and check for water in the d-sub connector. Troubleshooting Procedures bystronic laser error code list
Bystronic machines utilize distinct control interfaces depending on their generation, primarily Bystronic MMK, ByVision, or ByControl. Error codes typically appear on the Human-Machine Interface (HMI) accompanied by a numerical identifier and a brief text description.
| Code / ID | Description | Probable Cause & Solution | | :--- | :--- | :--- | | | Laser Gas Pressure | Laser gas bottle is empty or pressure regulator is faulty. Replace the gas bottle. | | L10 | Turbo Blower Failure | The vacuum pump/blower did not reach speed or overheating. Check the cooling water flow to the blower. Check for vibration. | | L20 | High Voltage Fault | Sparking inside the resonator. This can happen if the mirrors are dirty or the gas mix is incorrect. Check mirrors and vacuum system integrity. | | L30 | RF Driver Fault | The Radio Frequency generator (which excites the CO2 gas) has failed. Check the RF cables and the driver board. | | L55 | Cooling Water Flow | Flow switch not detecting water. Check the water pump, clean the filter in the chiller, and ensure the flow rate is sufficient. | : Manually close the mirror cover and adjust
Laser cutting generates massive thermal energy. The chiller loop must maintain strict temperature windows.
Record the Exact Code: Note the number and the accompanying text. : Clean the cutting nozzle holder with alcohol,
Disclaimer: The codes listed are based on common Bystronic platforms (BySprint, BySmart, ByStar) from 2005–2025. Fiber and CO2 variants may have specific sub-codes. Always verify with your machine's manual.

Linear motors and rotary drives monitor their own positioning continuously.
Specifically refers to low oil levels in the X1, X2, or Y axes. Checking the lubrication switch and refilling the reservoir usually clears these. 3. Cooling and Environmental Alarms
