Manufacturer reference linkedEdition check required

MODEL TROUBLESHOOTING

Start with the symptom, then follow the checks

Confirm the actual RAY5 10W controller firmware and software connection method; generic GRBL codes may not be supported by every firmware.

Before starting: Laser radiation can cause eye injury and fire. Follow the manufacturer's enclosure, eyewear and fire-safety rules; disconnect power before inspecting motion hardware.

Why does my LONGER RAY5 10W stop in the middle of engraving?

Start by separating job/software interruption from a loose USB connection and a machine overheat or motion fault.

Get step-by-step checks and outcomes →Why does my LONGER RAY5 10W move but not engrave?

If the head travels but no mark is made, verify job output settings and focus before calling the laser module defective.

Get step-by-step checks and outcomes →Why isn't the X-axis moving on my LONGER RAY5 10W?

With power off, determine whether the X-axis is mechanically blocked before investigating motor or firmware faults.

Get step-by-step checks and outcomes →Why won't my LONGER RAY5 10W connect to LightBurn?

Identify whether the problem is USB serial discovery or Wi-Fi configuration; each requires different settings in LightBurn.
