Insufficient pressure or incorrect mixing of assist gases like Nitrogen ( N2cap N sub 2 ) and Oxygen ( O2cap O sub 2 Common Bystronic Laser Error Codes and Solutions 1. Laser Source & RF Generator Faults
This guide provides a comprehensive overview of common , their meanings, and typical troubleshooting steps to get your ByStar , BySprint , or ByFlex machine back up and running. 1. Common Bystronic Laser Error Codes (CNC & Machine)
Mechanical binding on the linear rails, a lack of lubrication, or an overloaded drive motor. bystronic laser error code list
Often caused by a dirty cutting head, moisture on the contact print, or cracked ceramics.
Many Bystronic systems share a similar numerical coding logic for their resonator and cutting head systems. Error Code Issue Description Potential Cause & Troubleshooting Power Supply Fault
– Errors involving the table changer, nozzle changer, or automation systems. 2. Top Troubleshooting Scenarios W-Axis Warning Error (Common on ByStar 6kW)
Inspect the nozzle for physical damage or debris. Clean or replace it. The following codes and descriptions have been compiled
Power down the machine and check if the cutting head assembly shows signs of physical collision impacts.
Laser source shuts off within seconds of attempting to fire. Common Causes:
Empty premix gas cylinder or low supply pressure from line regulators. Leaks in the gas delivery lines leading to the resonator. Malfunctioning internal gas mixing valves.
Navigating Bystronic laser error codes usually starts at the machine's control interface. While the specific list of codes can vary based on your machine's generation (e.g., ByStar, BySmart, or older CNC97 systems), most errors fall into predictable categories like power, cooling, or the cutting head. Common Bystronic Error Categories Likely Causes W-Axis Warning Many Bystronic systems share a similar numerical coding
Check oil levels and the lubrication switch for the specified axis. Y-Axis Oil Level
