Overview

The Epilog laser is a laser cutting and engraving device. It can load thing materials such as wood, Plexiglas or cardboard and cut out various shapes and sizes from them. Aside from this it has a very powerful raster mode. The machine can take plates of up to 60 by 30 centimeters. Any vector design in the PDF file format can be cut out by the machine.

How to laser cut

Step 1

First you need a vector graphics file. You can make these files with programs such as Inkscape, Coreldraw or Adobe Illustrator. Make sure you save files as .pdf. Lines that you want cut should be 0.01mm thick. Everything else will be rasterized. Open the Document in Adobe PDF reader on the computer.


Step 2

Turn on the machine, the ventilation and the air pressurizer.


Step 3

Choose your material. It is always best to make a dummy version in cheap cardboard first, to see if you got your measurements and settings right. Put the material in the machine and make sure its straight and flat, and press the [X/Y OFF] button followed by the green [GO] button. Now proceed to move the laser to where you want it to start cutting. Bear in mind the machine starts at the top right corner of your design. If you are satisfied with the position you can press [SET HOME]. If you need help aiming press the [POINTER] button to get a red dot on the lasers position.


Step 4

Go back to the .pdf file and press the [CTRL]+[P] buttons to print. Click on the [PROPERTIES] tab to get the laser cutter's options. You will be taken to a special printing screen. Here you will need to determine the settings that correspond with the material you have chosen. See below for a table. Make sure you have [AUTO FOCUS] and [VECTOR SORTING] selected.


Step 5

Now select either [RASTER], [VECTOR] or [COMBINED] from the selection in the top center. Raster means engraving only, vector means cutting only, combined means both. The next step is to set the size of your design. You can select [PROPERTIES] from the [FILE] menu in Adobe PDF reader to check if you forgot. The last step is to set the raster and vector settings in the right side of the dialog window. Below you will see a table with the settings for the materials we use in the FabLab. When this is done you can press the [OK] button and then the green [GO] button on the machine.

Print options

Here are the Epilogs printing options. Here you chose what resolution you want, if you want raster(engraving) or vector(deeper cutting) cutting. When you are going to adjust the speed, power and freq, options look in the manual for the best settings. Then you choose the piece size, this is the size that you want you picture to be, NOT the size of material that is going to be cut. You also will need to choose a focusing option. Auto focus is the easiest.

Color Mapping

When you use color mapping you can set different options to different colors. To remove a color just mark it and hit the – button. To Add a color you hit the + button. You can also move the color up and down the list, the color that is at the top is the one that is going to get cut first. The speed, power and frequency options works in the same way, as in the general options.

Things to watch out for

Before you start cutting, open the glass door and turn on the pointer. Then you click print. If the red dot hit one of the ruler you need to adjust the x an y.

  1. Press X/Y OFF
  2. Press GO to disable X and Y axis (Press STOP to cancel and send the carriage back to its Park position if you change your mind!)
  3. Move the lens assembly by hand to your desired location (remember to turn the Red Diode Pointer on as a visual locator aid)
  4. Press SET HOME to establish your new home position. After you have set home, pressing the RESET button will move the carriage to its park position a short distance (approx.1/2 inch (12 mm)) to the front of where you set home.
  5. Once you are finished with your temporary home position, and want to restore the carriage to the upper left corner of the machine, press the Set Home key and the Reset key simultaneously. Press the GO key and the carriage will move back and to the left to its normal upper left corner Park position.

Good to know

If you are making press fit with acrylic on the laser it can be good to have extra 0,5 mm space so it will fit well together.

Safety


Fire safety

  1. NEVER let the Laser system operate if it will be unattended.
  2. KEEP the area around the machine clean and free of clutter, combustible materials, explosives, or volatile solvents such as acetone, alcohol, or gasoline.
  3. ALWAYS keep a properly maintained and inspected fire extinguisher on hand. Epilog recommends a Haltron fire extinguisher. Since it discharges a clean, easily removable substance that is not harmful to the mechanics or the wiring of the laser system.
  4. ALWAYS use air assist when vector cutting.
  5. BE CAREFUL many materials have the potential to suddenly burst into flames. Always monitor the machine when its operating.
  6. KEEP you laser system clean and free of debris. Regularly remove the vector grid to clean any small pieces that have fallen through the grid.

Laser safety.

  1. DO NOT disassemble the machine or remove any of its protective covers while the unit is plugged in.
  2. DO NOT attempt to defeat the door interlocks.
  3. DO NOT view directly into the beam of the laser diode pointer (red dot pointer).
  4. DO NOT operate the Laser Diode Pointer without the machine's focus lens in place. If the unfocused beam strikes a reflective surface, it could be directed out of the cabinet.

Electrical Safety

  1. DO NOT open any of the machine's access panels while the unit is plugged in. Opening a panel may expose the operator to the unit's AC input power.
  2. DO NOT make or break any electrical connections to the system while the units is turned on.
