Laser It Challenge #4: IRIS Camera - Bike Gear Jig Template

Welcome to this episode of the Epilog Laser It Challenge. Is it possible to jig and template using the IRIS Camera system?

  1. We’ll begin by placing a black matboard scrap and the chainring gear on the work surface under the Fusion Edge camera. Using a section of black matte board will provide high contrast between the metal chainring and the background, which is important for a good auto trace in a later step.

  2. Next, we’ll use the Auto Focus feature to focus the IRIS camera to the chainring for a life-sized image capture.

    close the lid and focus the chainring

  3. To collect an image capture with the IRIS Camera, open the Job Manager and click the Camera Options icon in the top right corner

    click the camera icon in the top right

  4. Select the Overhead Video option to open the IRIS Camera live video feed.

    select the overhead video

  5. The Overhead Camera feed provides a top-down view of the work area and includes an Automatic setting for brightness and contrast.

    We can also turn off the Automatic feature and adjust the brightness and contrast manually to achieve a custom result.

    For this example, we’ve turned off the Automatic setting and adjusted the brightness and contrast to achieve a high-contrasting result between our black matte board and metal chainring.

  6. With our brightness and contrast now optimized for image capture, we’ll select the Copy Background Image button to copy the IRIS Camera view to the computer’s clipboard.

  7. Now within CorelDRAW, we’ll paste our image capture into a new 24” x 12” document, then right click the image and select Edit Bitmap to open the image in Corel PHOTO-PAINT where are few more adjustments will be made.

    paste the background capture to coreldraw

    right click the image select edit bitmap

    open the image in corel photo paint

  8. Select the Crop Tool from the Toolbox on the left and draw a crop box around the chainring leaving a comfortable margin around the outside.

    select the crop tool

  9. At this point we’re going to clean up the teeth of our chainring using the Eraser tool. Doing so will provide a much better quality Vector Trace when we move back into CorelDRAW.

    cleaning up the chainring teeth

  10. Select the Eraser tool from the Toolbox on left and begin clicking and erasing any gray pixels seen on the tips of the chainring teeth.

    select the eraser tool

    The eraser tool comes with a few options to increase the size and shape of the tool, but for this example the default settings work out perfectly to match the curve on the tip of each chainring tooth.

  11. Once all the teeth of the chainring have been cleaned up, we’ll use the Invert Colors option in PHOTO-PAINT to invert the colors in our image capture.

    From the Menu bar at the top of the screen, select Image > Transform > Invert Colors to invert the image.

  13. Click on the black chainring image to create a selection of the chainring, then right click the selection and select Apply Smart Selection to Mask from the menu.

    click on the black chainring area

    apply the smart selection to the mask

  14. As a final step before moving back into CorelDRAW for our vector trace we’ll invert our mask selection by clicking the Invert Mask option from the Standard menu bar at the top of the screen.

    invert the selection to the background

  15. Then press Delete to remove the background.

    press delete to remove the background

  16. To finalize our image and move back into CorelDRAW, we’ll click the Finish Editing button in the Standard menu bar at the top of the screen, then select Yes when prompted to save changes to the bitmap

    finish editing

    yes to save changes

  17. Once PHOTO-PAINT has finalized our save, we’ll move over to CorelDRAW to create a vector tracing of our newly adjusted bitmap image.

    back in coreldraw

  18. Back in CorelDRAW with our image selected, we’ll select the Trace Bitmap button in the Property bar at the top of our screen and select Outline Trace > Low Quality Image from the options to open CorelDRAW’s PowerTrace feature.

  19. We’ll start by selecting the Color tab in the top right of PowerTrace, then setting our Color Mode to RGB and Colors to 2. These settings will simplify the image vector trace and give us a black and white only result.

    set color to rgb and colors to 2

  20. Next, we’ll go back to the Settings tab for a couple adjustments to our Detail and Smoothing settings.

  21. We’ll set the Detail to 100, and the Smoothing to 31 and click OK at the bottom of the screen.

  22. The PowerTrace feature isn’t perfect for all vector tracing projects, but for this black and white conversion and example, it works very well. Depending on various factors like brightness and contrast, bitmap capture DPI and lighting you may have to experiment with various PowerTrace settings to achieve the results you see here.

  23. Once our vector trace is complete, we’ll create a copy of our results and move them off to the side of our document area for use in a later step.

  24. To create our jig for the chainrings we’ll only need the outline of the chainring. To isolate the chainring outline, we’ll right click our vector group, select Break Apart from the menu options, then select the inner chainring holes we don’t need and press the Delete.

  25. With the chainring outline now isolated, we’re now going to create a jig with 4 columns and 2 rows of chainring holes.

  26. A quick note here, turning on the Alignment and Dynamic Guides under the View menu within CorelDRAW will make aligning and creating our matrix of jig holes much easier in the following steps.

  30. We’re now ready to print and cut our chainring jig at the laser. We’ll be setting up our laser Process settings for corrugated cardboard. There are many types of materials suitable for jig applications - wood, acrylic, engravable plastic, and cardboard for example. Corrugated cardboard is a great material for a one-time use jig as it’s readily available and inexpensive.

  31. We’ll begin this portion of our project by printing the file to the Epilog Software Suite.

  32. Within the Epilog Software Suite, we’ll adjust the following settings:

    Engraving Settings
    Machine: 60-Watt CO2 Fusion Edge 12
    Process TypeVector Kecepatan25 % Power100 % Frekuensi50 %
    (Be sure to check the recommended materials settings in your machine's manual.)

    Then Print the file to the laser.

    software suite settings

  33. At the laser we’ll load our 24” x 12” sheet of corrugated cardboard onto the bed of the laser system in the top left corner, close the lid, focus the material, and press the Go button to begin cutting the job.

  35. Now it’s time to prep our chainring parts for engraving.

  36. If we were using an Epilog fiber laser, we'd be able to mark directly on the chainring, but for this example we're using the Enduramark metal marking spray for CO2 lasers, a metal marking compound that gives our Fusion Edge with CO2 laser, the ability to mark on bare metal components and parts.

  37. We’ll layout the chainring parts onto a sheet of cardboard, then thoroughly cover the parts with the Enduramark Black spray until the part is uniformly covered with a single coat of the metal marking spray.

    applying spray to the parts

  38. Once the metal marking spray dries, we’ll place our chainring parts into our jig in preparation for laser marking.

  40. The artwork we’ll be using for the chainrings includes a serial number, data matrix code, logo, and chainring description text.

    file setup and artwork

  41. With our artwork ready to go, we’ll select only the artwork we’ll be printing for the job.

  43. In the Epilog Software Suite, we’ll leave the Process Type set to Engrave and adjust the perimeters for:

    Engraving Settings
    Machine: 60-Watt CO2 Fusion Edge 12
    DPI600 Kecepatan30 % Power100 % Pola Simulasi WarnaStucki Arah PengukiranBawah-Atas
    (Be sure to check the recommended materials settings in your machine's manual.)

    Then, we’ll click the Print button to send our marking job to the laser

    software suite settings enduramark marking

  44. At the laser, we’ll focus the laser to our chainrings, and begin the job by pressing Go

    press go to begin the job
