"Laser Module Overtemperature (E1 S40)" on LX2

🔥 Temperature Protection (What You Need to Know)

When this alert appears, the Laser Module has automatically paused to protect itself from operating outside its safe temperature range.
This is normal behavior and does not indicate a malfunction.
Once the temperature returns to the normal range, you can resume using the machine.

Problem Description

The Laser Module includes a built-in temperature protection feature. If the module temperature falls below 5°C (41°F) or rises above 55°C (131°F), the machine will automatically pause and display a temperature alert in LDS.

Why Temperature Protection Is Necessary

Operating the Laser Module outside its recommended temperature range may affect laser performance, processing quality, and long-term reliability. Temperature protection helps ensure stable operation and extends the lifespan of the module.

What Should I Do?

When a temperature protection alert appears:

(1) Wait for the module temperature to return to the normal range.

(2) Ensure the machine is being used in a suitable environment with adequate ventilation.

(3) No restart is required. The machine will become operational again automatically.

When the Temperature Falls Below 5°C (41°F)

The machine will automatically pause to prevent unstable laser performance in low-temperature environments. Once the temperature returns to the normal range, operation will resume automatically.

Low-temperature protection helps maintain stable laser performance and prevents abnormal operation in cold environments.

When the Temperature Rises Above 55°C (131°F)

The machine will automatically pause, and the cooling fan will run at full speed to help lower the module temperature. This is normal behavior. Once the temperature returns to the normal range, operation will resume automatically.

If high-temperature protection occurs frequently, improve ventilation around the machine and avoid prolonged operation in hot environments.
