  • Page 9: Section 2 - Installation

    SECTION 2 - INSTALLATION UNPACKING AND ASSEMBLING THE SYSTEM The laser engraving machine is shipped in one crate that contains the system, a cart with casters and various accessories. The following steps outline the unpacking and assembly of the system. Please follow these steps carefully.
  • Page 10 7. Attach the four black casters to the cart by threading the casters into the nuts that are welded onto the bottom of each leg. Tighten each caster in place with the 3/4 inch wrench. There are two locking and two non-locking casters provided. Make sure when attaching the casters that the locking casters are installed on the front of the cart.

  • Page 11: Operating Environment

    Attaching Cart to Laser System OPERATING ENVIRONMENT Before the system is installed, choose a suitable location. Follow the guidelines below: Avoid places where the system may be exposed to high temperatures, dust, or high humidity (humidity exceeding 70% or where the temperature is near the dewpoint).

  • Page 12: Exhaust System Requirements

    EXHAUST SYSTEM REQUIREMENTS To properly exhaust fumes and smoke from the laser engraving system during operation, it is necessary to provide an exhaust unit moving a minimum of 235 CFM at 6 inches of static pressure. Many industrial supply companies carry blowers that should meet these requirements. THROUGH OUR RESEARCH WE HAVE ESTABLISHED GUIDELINES ON THE PROPER CFM RATINGS REQUIRED FOR THE EXHAUST SYSTEM.
  • Page 13 We recommend installation of the exhaust system by a licensed contractor to meet safety and local code requirements. Please contact a local air quality control specialist. Again, if there are any questions, please contact our technical support.

  • Page 15: Computer Recommendations And Setup

    COMPUTER RECOMMENDATIONS AND SETUP The following computer configuration is the minimum requirement necessary to operate in the Windows environment. Using a computer with more speed, memory, and storage capacity will enable the graphic images to be produced faster. A faster computer will perform calculations quicker and will shorten download time to the laser system.

  • Page 16: How To Install The Uls Windows Printer Driver

    Cabling Connections HOW TO INSTALL THE ULS WINDOWS PRINTER DRIVER Installation of the ULS Windows Driver will allow Microsoft Windows version 3.1 to interface with the laser engraving system. This driver is installed the same way as most other Windows printer drivers, and a simple step-by-step installation procedure is outlined below.
  • Page 17 Add Unlisted Printers Dialog Box Insert the floppy disk containing the Universal Laser Systems Windows Driver into the appropriate disk drive and type the letter of that drive in the Install Driver box.

  • Page 18: Section 3 - Software Setup And Operation

    SECTION 3 - SOFTWARE SETUP AND OPERATION USING WINDOWS GRAPHICS SOFTWARE Page Setup To properly generate and position artwork, most graphics software will permit the customization of the page size and orientation. Set the page orientation, in the graphics software to Landscape, and the page size to a horizontal length of 17 inches and vertical length of 11.5 inches.
  • Page 19 driver, the colors that are used MUST exactly match the colors listed in the driver. The colors are black, red, green, yellow, blue, magenta, cyan, and orange. Some programs will provide these basic colors pre-defined and other programs may require the creation of each of the colors by defining them in CMYK percentages.
  • Page 20 engraving thick outlines is desired. The outline thickness at which the driver will interpret cut lines as filled objects is dependent on the software used. Usually, any line thickness .008 inches or greater will engrave. The only way to determine the cross over point for line thickness is to experiment with different line widths.
  • Page 21 Hidden Vector Lines in Artwork The ULS Windows printer driver does not automatically filter out outlines that are overlapped by engraved objects such as fills. If there are filled objects with some hidden outlines underneath the filled area, the laser system will then engrave out the fill and cut the hidden outline on top of the fill. This is a common occurrence when using pre-drawn ClipArt designed for laser printers.
  • Page 22 When scanning black and white images, scan at the highest DPI that the scanner allows. The higher the DPI, the smoother the image will be. Scanning in at 300 DPI is the minimum recommended resolution for scanning line art (monochrome bitmaps), but 600 DPI provides a significant improvement in the image quality.

  • Page 23: The Uls Windows Printer Driver

    THE ULS WINDOWS PRINTER DRIVER The ULS Windows Printer Driver NOTE: When the following sections refer to turning a switch ON, this means putting an " X" in the box next to the driver selection desired. Turning a switch OFF signifies removing the "X" from the box. To change the POWER, SPEED, and PPI of a color, position the mouse arrow on the color and click once with the left mouse button.
  • Page 24 SPEED SETTING This setting controls how f ast the motion system moves in a percentage of the maximum speed of the system. For example, 100% SPEED is equivalent to 16.5 inches per second straight line velocity. Therefore, 10% SPEED is equal to 1.65 inches per second. When engraving, this is the rate in which the motion system moves back and forth.
  • Page 25 ADVANCED Turning this switch ON will permit the changing of the PPI settings. If the switch is turned OFF, the word AUTO will appear in the PPI column and will be colored gray. Since 500 PPI is the setting that is used most often, AUTO sets the PPI to 500 automatically and does not allow change unless the ADVANCED switch is turned back ON.
  • Page 26 In order to engrave photographs and ClipArt that use colors and greyscales for shading, a halftone pattern must be created. A halftone is a series of dots arranged in a specific pattern. By varying the size and intensity of these dots, shading can be simulated in a process that is similar to that used to generate newspaper photographs.
  • Page 27 RUBBER STAMP and INVERT FILL These two selections will only appear in the driver if the Rubber Stamp option has been purchased. For a full explanation on how to use this option, refer to section 4.7. Again, please read the rest of this manual up to that point before attempting to use this option.

  • Page 28: Using Dos Based Programs

    USING DOS BASED PROGRAMS When using DOS based programs, there are a f ew things to keep in mind. DOS software is not standardized and each application will work differently. When using DOS applications, it is not possible to print through the ULS Windows printer driver and for this situation, the system has been designed to automatically emulate a Hewlett Packard plotter.

  • Page 30: The Main Control Panel

    THE MAIN CONTROL PANEL The main control panel on the ULS laser engraving system provides easy access to all of the controls necessary for cutting and engraving operations. The control panel consists of a liquid crystal display (LCD), indicator lights, buttons, and a laser ON/OFF switch. The control panel is divided into three sections: Menu System and Controls, Process Controls and Laser ON/OFF controls.
  • Page 31 The Menu system All of the features built into the laser cutting and engraving system can be accessed and controlled through the menu system. The menu system is divided into four general areas each of which is accessed through the main menu. The main menu will display when the system is turned on. To access the submenus of the menu system from the main menu, select it with the cursor (move the cursor with the arrow keys) and press SELECT.
  • Page 32 The # OF COPIES feature on the second line indicates the number of times the current file has been used since it was loaded into the buffer (the system keeps a running count of the number of times each file in the buffer has been processed). The second line also contains a timer to time files as they are run (this is useful for costing jobs).
  • Page 33 restore it to the original setting. It is possible to adjust the settings while engraving on some scrap material until the desired POWER, SPEED, and PPI settings are obtained. Note these settings, change them in the ULS Windows printer driver and resend the file to the laser system for the final run. Lastly, the laser system allows eight different power settings to be saved in memory and used when processing a DOS based file.
  • Page 34 the screen is always the currently active file and there are two methods for looking through the list of files and choosing another file. The first method is to press the NEXT FILE button on the control panel. Each time the NEXT FILE button is pressed, the next file in the buffer becomes the current file. The second method is to point the screen cursor at the file name and press the SELECT key which will move the cursor to the right, then use the arrow keys to move backward or forward through the list until the file desired is displayed and then press the SELECT key again.
  • Page 35 The SETUP submenu The SETUP menu choice allows laser system reconfiguration. Selecting this option will lead to other menu choices. Then TICKLE is the term used for small pulses which are fed to the laser to keep the plasma inside energized.
  • Page 36 The CONFIGURATION selection allows the reconfiguration of certain features of the engraving system. Selecting this option will lead to other menu choices. AUTO POWER and BUZZER menu options can be toggled either ON or OFF by placing the cursor on the appropriate menu choice and pressing SELECT. The AUTO POWER feature allows the laser system to change power settings while it is cutting and engraving a file.
  • Page 37 Two ports are provided on the right side of the system for interface with a computer, a serial and a parallel port. Only one port can be used at a time. To activate a port, select PORTS from this menu and one of the following sub menus will appear: The menu that appears indicates the currently active port on the laser system.
  • Page 38 The LOAD DEFAULTS selection on the last line returns the system to its factory default settings. WARNING: Do not select the LOAD DEFAULTS menu selection without first consulting a ULS technical support representative. The DIAGNOSTICS selection allows the testing of certain features of the engraving system. Selecting this option will lead to other submenus.
  • Page 39 By selecting RETAIN SETTINGS, any and all changes made to the display settings will be permanently stored even if power is turned off to the laser system. Those settings will be retained in the laser system until they are changed and RETAIN SETTINGS is selected again. THE PROCESS CONTROLS FILE RUN FILE...

  • Page 40: Motion System Controls

    THE LASER CONTROLS The LASER ON/OFF switch allows the laser’s power to be turned on and off manually for emergencies. The red indicator light will light up when power is being supplied to the laser. The indicator light is also tied in with the safety interlock system, so the light will go on and off as the doors to the system are opened and closed.

  • Page 41: Loading And Focusing The Laser System

    LOADING AND FOCUSING THE LASER SYSTEM Loading materials The first step to laser engraving is loading the material and focusing the laser beam on the top surface. Let’s use a 4 x 6 inch wooden plaque as an example. Open the top door and place the wood on the engraving table.

  • Page 42: Front View

    Observe the top of the focusing tool. Now raise the engraving table until the focusing tool just starts to tilt away from the lens holder as shown in the diagram below. Back the engraving table down again slightly so the focusing tool again sets flat against the side of the lens holder. The point in which the focusing tool just starts to tilt away is the optimal focus distance.

  • Page 43: Running A Sample

    RUNNING A SAMPLE The following outline is a step by step procedure used to produce a laser engraved object. Please follow this procedure to understand the steps necessary for laser engraving. STEP 1 Turn on the computer and then the laser system. Be sure to turn the equipment on in this order.

  • Page 44: Using The Optional Rotary Fixture

    USING THE OPTIONAL ROTARY FIXTURE The Rotary Fixture controls in the ULS Windows printer driver are used along with the optional Rotary Fixture to engrave onto round or cylindrical objects. In order to compensate for different diameter objects, the image must be adjusted. This is done automatically by the ULS Windows printer driver when selecting Rotary Fixture and entering in the diameter of the object being engraved.
  • Page 45 Connect the Rotary Fixture control cable to the connector on the laser engraving system. To find the connector, follow the ribbon cable which moves with the main arm of the motion system back to its source on the side wall up underneath the protective overhang for the main arm of the motion system.
  • Page 46 Before loading the glass into the fixture, measure the diameter of the glass in the area where the engraving is to be located by using a caliper or similar measuring device. Remember this number or write it down. Place the open end of the glass on the right side of the Rotary Fixture. Lift the lever on the adjustable end of the fixture and slide it up against the other end of the glass so the glass rests firmly against the padded foam disk.
  • Page 47 The laser system is now ready to be powered up. Turn on the laser and note that when the laser system goes through it’s homing procedure, the focus carriage does not move but the Y-axis arm slides all the way to the right. This is because the Y-axis motor has been disconnected when the Rotary Fixture was installed.
  • Page 48 Position the graphic, on screen, so that it will fit vertically within the new page height and horizontally within the engraving area of the glass. If the graphic does not fit within the vertical page size limits, the portion that is outside the page limit will not engrave. Remember, the new page size that the driver calculates from the diameter of the glass is it’s actual circumference.
  • Page 49 The graphic on screen will now need to be adjusted. The graphic will have to be rotated another 90 degrees so that the graphic is upside down. Reposition it within the defined engraving area as the diagram below illustrates. Do nothing to the Rotary Fixture inside of the laser. The setup on it is the same as in Landscape mode.

  • Page 50: The Rubber Stamp Option

    THE RUBBER STAMP OPTION There are two switches in the ULS Windows printer driver which manage the rubber stamp option, the RUBBER STAMP switch and the INVERT FILL switch. The RUBBER STAMP selection taper profiles the engraving and automatically mirrors the entire page about it’s centerline. The INVERT FILL switch will turn the entire page into a negative while it is printing.
  • Page 51 example. The following diagram shows an example of setting up the graphics software’s page layout and positioning the rubber engraving material inside the laser system respectively. After making all driver selections, print the graphic to the laser system. Start engraving and notice that the stamps are being engraved as a mirrored image and are in the correct position on the rubber sheet.
  • Page 52 When all engraving is done, the stamp gets cut out along the red cut line due to the higher power setting that was assigned in the driver for the color red. The second method is to create a full sheet of rubber stamps and engrave them all at the same time. First create a stamp as a positive image as shown below.

  • Page 53: Start Up Parameters For Various Materials

    START UP PARAMETERS FOR VARIOUS MATERIALS This section provides driver settings and helpful hints to get started engraving and/or cutting various materials. These settings are to serve as a starting point and are not necessarily optimized for each particular application. There are many variables that can affect the cutting and engraving process such as differences in the thickness of the material, density of the material, composition of the material, and the manufacturing processes used to make the material.

Leave the masking on the non-engraved surface to prevent accidental scratches. TYPE POWER SPEED PASSES DEPTH RASTER ENGRAVING (deep) .010”...
  • Page 55 without causing damage. Engraving lightly and without masking seems to be the better all around alternative. If only cutting acrylic, extruded works better and is less expensive than cast. The cut edges of extruded acrylic will appear to be more highly polished and clearer than cast acrylic when laser cut. When cutting acrylic, it might be necessary to remove both sides of the original masking and re-mask with transfer tape if cutting through the original masking produces flaming.

  • Page 57 residue to form just like with non-mirrored acrylic. A double image will appear if engraving on the front side of the mirror. It is not necessary to mask the backside when engraving because the mirrored backing shields the acrylic from smoke damage. To cut mirrored acrylic, it might be necessary to remove all original masking, re-mask with transfer tape, and dampen the tape with water from a spray bottle.
  • Page 58 ANODIZED ALUMINUM TYPE POWER SPEED PASSES DEPTH RASTER ENGRAVING .001” COMMENTS: The power required is dependent on the thickness of the anodized coating. Do not overpower because the anodized will either be dull in appearance or the engraving lines will be too thick.
  • Page 59 BRASS - COATED TYPE POWER SPEED PASSES DEPTH RASTER ENGRAVING 1000 .002” COMMENTS: Engrave unmasked. Use a light setting to engrave through the coating. Using 1000 PPI seems to have a cleaner removal of the coating. Some thicker coated brass will require more power.

To engrave deeper it is recommended to make more passes instead of reducing speed.
  • Page 76 sponge. We recommend using a kitchen sponge with a nylon string mesh wrapped around it. Dampen the sponge and wipe off the residue. A damp chamois cloth works well also. Do not use paper towels or a regular sponge because these materials will get lodged in the engraved area when wiping and are extremely difficult to remove.

  • Page 77: Section 5 - Basic Maintenance

    SECTION 5 - BASIC MAINTENANCE GENERAL CLEANING OF THE SYSTEM A visual inspection of the machine should be done at least once a day. If dirt or debris is present a general cleaning should be performed. The frequency of cleaning will depend entirely on the type of material being cut or engraved.

  • Page 78: Optics Cleaning

    To clean the exhaust, remove the exhaust panel from the inside left wall of the system by removing the four screws on the front of the panel. When replacing the panel, make sure to press it tightly into place while tightening the screw so that the panel makes a good seal with the system. Check the intake air filter on the outside right wall of the system.
  • Page 79 Sit down in front of a table and remove the lens from the lens holder by holder it in your left hand and a clean sheet of lens tissue flat in your right hand.
