Read laser-source alarms and logs¶
Use source software as a read-only evidence tool unless Gweike or the source manufacturer gives serial-number-specific instructions. An alarm is a protection signal, not an obstacle to clear blindly.
No internal source service
Do not open the laser source, defeat its interlocks, change/decrypt protected parameters, or energize it without correct cooling and safety systems. High voltage and stored energy may remain after isolation; optical damage can create hazardous emission.
Prepare¶
- Record the source brand/model/power/serial and machine serial.
- Capture the exact mLaser/chiller/source indicators and timestamp before restarting.
- Obtain the diagnostic application and connection instructions for the fitted source from Gweike/the source manufacturer.
- Use the specified interface. The M-Series manual demonstrates a USB-to-RS232 diagnostic connection for the covered source workflow; your source/port may differ.
- Keep the machine in the safe non-emitting state specified for diagnostics and maintain cooling if the source procedure requires it.
Connect without changing configuration¶
Install only the trusted adapter driver/software, connect to the documented source diagnostic port, and select the correct communications settings. If the port does not open, check Windows device recognition, COM-port selection, cable/interface, and whether another application owns it. Do not try random baud rates or ports on energized equipment.
Capture useful evidence¶
Read and save or photograph:
- current operating/status words and active alarms;
- event/fault history with timestamps;
- runtime, temperatures, flow/ready states exposed by the supported tool;
- software/firmware identification;
- state transitions during one safe reproduction, only if approved.
Export logs in their native form where possible and keep an untouched copy. Note machine/chiller state and local time so Gweike can correlate events.
Interpret by system, not just code text¶
Group an alarm into cooling/temperature, supply/power, communication/control, interlock/safety, optical/back-reflection, or internal source fault. Verify external prerequisites that are safe and documented: chiller state/flow, connectors, machine ready/interlock state, and source control communication.
Do not repeatedly reset a thermal, optical, back-reflection, or internal hardware alarm. If it returns after external conditions are verified, leave the source disabled and send the evidence to Gweike. Only the documentation for the exact source model/firmware can define a code reliably.
Support package¶
Include source and machine identities, logs, exact code/text, timestamps, recent process/material, cooling/gas state, whether it happens at enable/pierce/steady cut, and any event preceding it. Avoid posting source service credentials or protected diagnostic files publicly.
