Why Does My LONGER RAY5 10W App Show an Upload Error?
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: RAY5 app upload failures may be linked to SD card formatting, card content, Wi-Fi/app connection or communication between controller and card.
What to do
- Use a known compatible SD card formatted in the manufacturer's supported filesystem and store a small correctly named test engraving file in the expected location.
- Reseat the card with power off, retry a short transfer from the intended LONGER app/network and compare with USB connection if supported.
- Replace a damaged or unreadable card before blaming the mainboard.
Still not fixed? Continue to the next check.

If the problem remains after the first checks
What to do
- If only one file fails, export it again with the proper controller/G-code format.
Confirm the repair
The machine lists and executes a small safe test job from SD without upload or parsing error.
