8. Safety Guidelines
Operating a laser engraving machine requires strict adherence to safety protocols to prevent injury and damage.
- Eye Protection: ALWAYS wear the provided safety goggles or equivalent certified laser safety glasses when the machine is in operation. Direct exposure to the laser beam can cause severe eye damage.
- Ventilation: Ensure adequate ventilation in your workspace. Laser engraving can produce fumes and particles that may be harmful if inhaled. Consider using an air assist system or an enclosure with exhaust.
- Fire Safety: Keep a fire extinguisher nearby. Some materials can ignite during laser processing. Never leave the machine unattended while operating.
- Material Compatibility: Only engrave or cut materials known to be safe for laser processing. Avoid materials that produce toxic fumes or are highly flammable.
- Safety Anti-Tilt Function: The Comgrow Z1 is equipped with a safety anti-tilt function. If the machine tilts beyond a certain angle, it will automatically trigger an alarm and stop carving to prevent accidents. The sensitivity of this function can be adjusted.
- Limit Switches: The Z1 features X and Y-axis dual limit switches. These prevent the axes from hitting the edges of the machine, protecting the device from damage.
- Children and Pets: Keep children and pets away from the operating area.
