The laser power fluctuates during engraving, causing inconsistent depth.
Troubleshooting Steps
- Check that the power supply is stable and avoid voltage fluctuation.
- Check that the laser module is cooling properly (is the fan running?).
- Check whether any cable is making poor contact.
- Confirm the software power setting is constant.
- If it remains unstable, the module may be aging — contact after-sales support for inspection.
