  • Page 44: Initial Testing

    4 Initial Testing Wear safety glasses during the entire test process! Always make sure the path is clear between the laser and its target. Never allow foreign objects between the laser and the material being engraved. Take care not to leave any part of your body in the laser path when it is in operation.

  • Page 45: Cover Shutoff

    4.2 Cover Shutoff Because of the risk of blindness, burns, and other injuries from direct exposure to the invisible engraving beam, this device shuts off the laser automatically when any one of its protective interlocks is triggered. Always make sure the path is clear between the laser and its target. Never allow foreign objects between the laser and the material being engraved.

  • Page 46: Water Shutoff

    4 Initial Testing 4.3 Water Shutoff Because of the danger posed by an uncooled laser tube, this engraver also shuts off the laser automatically when its sensors do not detect the correct water flow. You should test that the water shutoff functions correctly.

  • Page 47: Air Assist

    4.4 Air Assist Because of the danger posed by sparks during engraving and the risk of damage to the laser nozzle and focus lenses from fumes and debris, the pressurized air begins to blow from the laser head when the engraver starts engraving. You should test that the pressurized air blows correctly: Make sure that the air assist is in good condition.

  • Page 57: Instructions For Specific Materials

    5.6 Instructions for Specific Materials The following instructions are suggestions to help speed safe work with a range of materials. The user should research the specific safety and engraving requirements of their specific material to avoid the risk of fire, hazardous dust, corrosive and poisonous fumes, and other potential problems. Once the product is known to be safe or appropriate protective equipment has been set up, it can be helpful to engrave a test matrix of small boxes produced at various speed and power settings to discover the ideal settings for your design.

  • Page 58: Paper And Cardboard

    5 Typical Operation Sequence 5.6.5 Paper and Cardboard When engraving various paper products, generally use low to moderate power and fast speed. Test samples from each batch, as only small parameter differences can separate effects that are too light from those that burn through the substrate. As with leather, be especially attentive of the possibility of fire, as well as the dust produced in repetitive applications.

  • Page 59: Wood

    5.6.10 Wood As with rubber, there is a huge variety of woods and testing your specific material is essential to get the best results. In general, wood with consistent grain and coloring engraves more evenly. Knotted wood produces uneven effects, while resinous wood produces greater edge contrast. Some soft woods like balsa, cork, and pine engrave well (albeit with low contrast) at low or moderate power settings and high speed.
