Why Is My LONGER RAY5 10W Laser Suddenly Engraving Faintly?
Exact model: LONGER RAY5 10W
Safety: Disconnect power before opening the controller or laser head. Use wavelength-appropriate laser eye protection for testing.
A.
Start with the accessible checks
What this suggests: Weak engraving is often a contamination or focus problem.
What to do
- Turn off/unplug and allow the head to cool.
- Following LONGER's head-cleaning procedure, remove the nozzle and protective optical element using the head revision's specified tools, clean deposits with appropriate optical materials and reinstall without fingerprints.
Still not fixed? Continue to the next check.

If the problem remains after the first checks
What this suggests: A dirty RAY5 10W protective lens and nozzle can reduce power at the material even when laser output commands are unchanged.
What to do
- Clear air-assist restrictions, then set the correct working distance for the actual new/old head design.
- Use the same scrap, settings and material for before/after comparison; replace an optically damaged part rather than increasing power to compensate.
Confirm the repair
The test engraves evenly at its previous settings with no hazy beam spot or head overheating.
