![]() The software used to layout the images (Adobe Illustrator or Inkscape) can support both raster and vector images, and the machines can handle both types of jobs simultaneously. The software management program is not installed, and so the option should be unchecked. Send to Laser has to be on or it won't actually send the file to the machine. Send to Laser/Send to Manager: This tells the software driver where to send the data - to the machine and/or to a management program.Please see the Advanced Techniques page here for more information. Center Engraving: A way of manually setting the XY origin of the laser, which is useful in situations where the material does not fit neatly into the upper left corner.Unfortunately it does not work, and therefore this setting cannot be used and should never be turned on. Auto Focus (Library 21c Only): This setting would, in theory, automatically adjust the bed height so the focusing key would not be necessary.Therefore, it is recommended that any vector line that should be cut has the minimum thickness possible (0.025mm in Inkscape and. The threshold for "too thick" varies and is determined by the DPI setting. Tip 2: If a vector line is too thick, the software will convert it to a raster image and engrave it. Therefore, unless your image was made at 1200 DPI, it will most likely be a waste of time to run it higher than 600 DPI. Setting one of these images to 600 DPI will result is significantly better quality than if it was engraved at its native resolution, however you will probably not notice an improvement between 6 DPI. Most images are made at between 72 and 300 DPI. Tip 1: The machine can up-scale an image, but only to a certain degree. This only applies to raster images, as vector lines do not have a resolution in the traditional sense. a 1200 DPI setting will take twice as long as a 600 DPI setting for the same image. ![]() It is also important to note that the higher the DPI, the longer the runtime. DPI can range from 75-1200, and can result in significant differences in image quality. Resolution is measured in dots-per-inch, much like a typical paper printer. Since presets are used, this setting is not necessary or ideal. Frequency Automatic : This forces the laser to always run at a frequency of 5000hz.While this may result in lines being cut in a seemingly random order, it helps prevent the material from over heating and does not significantly increase cutting time. Vector Sorting : Rather than processing vector lines in the order they are listed in the SVG file, this lets the Epilog software determine the best order.Altering it significantly will usually result in the material not reacting to the laser as expected. What settings works best depends on the material, and therefor it is inadvisable to change in most circumstances. Frequency: The pulse rate of the laser.Speed & Power: The same as in the Raster Setting - speed is how fast the lens moves and power is the strength of the laser."Standard" works in almost all cases, but other settings can work better with photographs. Image Dithering: The pattern used for converting pixels to laser pulses.When using the Air Assist, it helps reduce smoke if it is on Bottom-Up. Engrave Direction: Whether the engraving starts with the top or the bottom of the image(s).The higher it is, the more pronounced the engraving, but too high can cause scorching and other types of damage to the material. This results in deeper and more pronounced engravings, but can also cause scorching or melting. The slower the speed, the longer the laser will stay in one spot. Speed: The speed that the lens moves back and forth.While there are a lot of settings, most jobs only require changing a few - usually speed, power, and piece size. Tip: Bring in extra material so you can run multiple tests to determine the best settings. Do not adjust the speed or power by more than 10% each time. If it is your first time using the material, you should start with the presets and only make minor adjustments until you find a setting that works safely. Once you've loaded the material preset, you can adjust settings as you need.
