1. Introduktion
The Ortur Laser Master 2 LU1-4 is a versatile CNC laser engraving and cutting machine designed for precision work on various materials. Equipped with a 32-bit motherboard, it offers enhanced speed and accuracy for both hobbyists and professionals. This manual provides essential information for the safe and effective operation, setup, and maintenance of your device.
2. Sikkerhedsoplysninger
Operating a laser engraver requires strict adherence to safety protocols to prevent injury and damage. Always prioritize safety.
- Øjenbeskyttelse: Always wear appropriate laser safety goggles when the laser is active. While the device features an eye-protection design, direct viewing of the laser beam should be avoided.
- Unauthorized Movement Detection: The main board includes a G-sensor. If the machine detects unauthorized movement during operation, the laser beam will automatically stop to prevent accidents.
- Connection Interruption Safety: In the event of a computer system stop or USB cable disconnection, which causes the laser engraver to cease movement, the laser beam will automatically stop to mitigate fire risks.
- Motor Stop Safety: If the laser engraver is under control but the user forgets to operate it, and the motor stops moving while the laser beam remains active, an additional safety mechanism will cut off the laser to prevent fire.
- Ventilation: Sørg for tilstrækkelig ventilation i dit arbejdsområde for at fjerne dampe og røg, der produceres under gravering og skæring.
- Brandfarlige materialer: Exercise extreme caution when working with flammable materials. Never leave the machine unattended during operation.
