  • Page 18: Installation

    3. Installation 3.1 Installation Overview A complete working system consists of the laser engraving cabinet, both laser nozzles and their accessories, the integrated cooling system, a ventilation system adequate for the materials you’re working (fan and ducts included), all applicable connection cables, and the laser and access keys. The cabinet can use designs provided by the enclosed engraving software by direct or internet connection with your computer.

  • Page 19: Unpacking Your Engraver

    If you have not already done so, finish removing the crate from around your engraver. Note that your chiller is not prefilled with coolant. ALWAYS check the chiller’s coolant level before turning the power on. Use antifreeze as needed. It is recommended that you use OMTech antifreeze for optimal performance.

  • Page 20: Electrical Grounding

    3.4 Electrical Grounding This device employs a powerful laser. As discussed in the Safety Information above, it is extremely high voltage and potentially dangerous, so users must securely ground it to avoid the buildup of static electricity. Using a standard 3-prong outlet will provide sufficient grounding.

  • Page 21: Exhaust System

    5. For initial use, press ⯆ to speed activation of the compressor. The default setting is to keep the chiller within 3.6°F (±2°C) of 77°F (25°C). 6. To change the target temperature, press SET, use ⯅ and ⯆ to adjust the value up or down, and press RST to save your changes.

  • Page 22: Main Power Connections

    3.7 Main Power Connections Confirm that the labeling beside the connection sockets matches your power supply. If you have not already done so, connect one end of the power cables to the connection sockets and the other ends to grounded outlets. The combined electrical load of all the major components of this device will draw over 30A.

If the laser continues to fire, the laser key is not working and must be replaced before the engraver can be used.

  • Page 37: Security

    Water Shutoff Because of the danger posed by an uncooled laser tube, this engraver also shuts off the laser automatically when the water cooling system malfunctions. After ensuring that the emergency stop button and cover protection both work, you should also test that the water shutoff works properly before conducting any other work on your machine.

  • Page 38: Operation

    4. Operation 4.1 Operation Overview Operate this laser engraver only in accordance with all the instructions provided in this manual. Failure to follow the guidelines detailed here can result in property damage and personal injury. You can control your engraver directly from the built-in control panel, through a direct USB cable connection with your computer, or over the engraver’s in-built Wi-Fi module.

  • Page 39: Typical Operation Instructions

    4.2 Typical Operation Instructions Step 1. Create the design that you’d like to engrave or cut into standard materials. (See §4.3 for engraving circular objects.) You can do this directly in your engraving software or use any other graphics program to create the image and set its engraving parameters.

  • Page 40: Rotary Operation Instructions

    Store everything neatly away. 4.3 Rotary Operation Instructions The base model of the PRO 2440 does not come with a rotary axis but is compatible with standard four-pin models. To use a compatible rotary axis, remove the steel saw bed, place your rotary axis in an open area, and connect its cord to the rotary port at the back of the main bay.

    5.3 File Management System Memory Files In the main menu, tap “File”, and the following menu pops up. Files are listed in the left column and a preview of a selected file is shown in the graphic display area. When there are multiple files, use the up and down icons to scroll through the file list.

  • Page 46: Setting Speed Levels

    USB Files The system is compatible with FAT32 and FAT16 USB file formats. For best results, however, store your files under the root directory of the USB flash drive so that the system can recognize them quicker and easier. By default, the system dissects a file name exceeding 8 characters and shows it in more than one word. Also, the system cannot recognize file whose names consist of characters other than English and Arabic numbers.

  • Page 47: Setting Power Levels

    5.5 Setting Power Levels All powers are displayed as percentages (%) of the engraver’s rated power. Running your laser above 70% risks shortening your laser’s service life. If you find power settings of 70% or lower do not produce the results that you need, for most materials it is better if you first attempt to increase the amount of energy per unit area by slowing the laser or running more loops before further increasing the power setting itself.

    6. Maintenance 6.1 Maintenance Overview The use of procedures other than those specified herein may result in hazardous laser radiation exposure. Before any cleaning or maintenance work, always switch off the device and disconnect it from its power supply. Always keep the system clean, as flammable debris in the working and exhaust areas constitutes a fire hazard.

  • Page 67: Cleaning The Mirrors

    3. Remove the air assist hose and the guide wire from the laser nozzle. 4. Loosen the bolt in the upper part of the laser head that holds the middle part in place. 5. Carefully slide the middle part of the laser head out and remove the lens from its casing. 6.

  • Page 68: Refilling

    NEVER touch or adjust your laser’s water supply while it is still turned on or connected to power. Your chiller should arrive with no prefilled coolant or antifreeze. It is recommended that you use OMTech laser-safe antifreeze for safety. Always fill the chiller with distilled water or a custom-purpose laser-safe antifreeze. Using deionized or tap water for any purpose but rinsing out cleansers (see §6.2.5 above) will gradually degrade the quality...

  • Page 69: Laser Tube Alignment

    6.4.1 Laser Tube Alignment 1. To test the alignment of the laser tube with the 1st mirror, cut out a piece of tape and place it on the mirror's frame. DO NOT place the tape directly onto the mirror. Turn on the machine and set the power level to 15% or lower.

  • Page 70: 1St Mirror Alignment

    6.5 Error Messages The chiller may display the following error messages: Code Meaning Typical Solution(s) Cool the area directly around the engraver. Pause work until the room itself cools. Ultrahigh Room Temp. Alarm Move the engraver to a cooler area. Contact customer service for information on checking the wiring for the chiller’s ambient temperature sensor.

  • Page 73: Parts Replacement

    6.6 Parts Replacement This engraver should not be modified or disassembled by anyone except trained and licensed professionals, but some consumable parts may require replacement after prolonged use. Contact your vendor or our technicians if you have any questions about fitment or installation. Using incompatible components is highly dangerous and waives all the manufacturer’s liability for any damage or injury caused.
