Safety Features

Longer Laser B1 30W Review 11

The LONGER Laser B1 30W laser engraver prioritizes safety with its eight installed safety protection features, ensuring a secure and user-friendly experience. Here are detailed descriptions of each feature:

a) Flame Detector

While laser engraving, it is a common practice to send a job to the engraver and allow it to continue working while attending to other tasks. However, it is important to be aware of the potential risks associated with this approach, as fires can occasionally occur due to various factors such as incorrect configuration settings or the use of low-quality materials.

When the Longer Ray 5 10W laser engraver detects flame, it will automatically stop and beep. This prevents any potential fire hazards from razing down your workshop.

b) Move Detection

This safety feature automatically shuts down the laser when any unintended movement is detected. It prevents accidental activation or operation, reducing the risk of injuries or damage.

c) Offline Safety

The offline protection feature ensures that the laser automatically shuts down when a disconnection or interruption in data communication occurs for over 15 seconds. It prevents any potential hazards that may arise from interrupted or unstable connections.

d) Security Lock

The security lock feature allows you to activate a lock mechanism to prevent unauthorized access or usage of the laser engraver. It ensures that only authorized individuals have control over the machine, enhancing safety and security.

e) Eye Protection

The eye protection feature is designed to safeguard against the laser’s potentially harmful effects on the eyes. The laser head has a protective acrylic cover that can quickly prevent burning in case of an accident. This minimizes the risk of eye injuries.

f) Emergency Stop Button

The emergency stop button provides a quick and easily accessible means to immediately halt all laser operations in case of emergencies or unexpected situations. Pressing this button instantly shuts down the laser, ensuring swift intervention and preventing any potential hazards.

g) Zero Reset

The zero reset feature automatically resets the laser head to its starting position, often referred to as the zero point or home position. This helps prevent burnout or damage to the material being engraved when accidental fires or anomalies occur during the engraving process.

h) Motionless Protection

The Laser B1 is equipped with an essential safety feature known as motionless protection. If the laser module remains frozen or inactive for a duration exceeding 15 seconds, the engraver will automatically shut off. This precautionary measure is crucial in preventing potential accidents in the workshop that may arise if the laser were to remain on without any operational activity.

Laser Lens Protection
