Using Inkscape with Cutters/Plotters Remove overlap of images for laser

    I am trying to take a log and load it into lightburn to engrave it. The problem is that the logo is a bunch of layered images. When viewed in inkscape it looks fine but the laser sees the parts of the image behind the front images and tries to laser both of them. svg file is attached. i need to make it so that what is visible is all there is. no overlapping of images.

    Inkscape has a new view mode "split" which makes it easy to see the geometry that needs to be corrected for laser cutting.

    There are a number of methods to reach the goal. One nice new feature is Inkscape's Shape Builder that helps isolate overlapping geometry. 

    I'd try to get all the geometry as unclipped paths and use the Shape Builder to refine the image.

    You might wind up with something like this:

    Original on the left, revised on the right.

     

    I've applied random colors to each path to indicate they are individual pieces. 

    Some additional combining could be done; e.g. the crucifix upper-right quadrant could be combined with the outline around the letters, and the small details at the bottom could be combined.

    Thank you for the info. I'm pretty new to insckape and still trying to figure out exactly how you did what you did but haven't had much time to work on it. Is there any chance you could send me the SVG file of what you did. I would be willing to compensate you.for it if needed. I have a friend who wants a couple things made before the holidays and I don't have the time to fix the file before that. I typically just make.stuff with files that are ready to laser but trying to expand a little bit. Thanks for your help

    How about this:  If you make a $100 donation to the Inkscape project (not to me), I'll send you the revised svg file and post a video tutorial to this thread on how this was accomplished.

    Techniques include:

    • Guides
    • Node editing
    • Groups
    • Snapping
    • Path operations
    • Locking and unlocking objects
    • Path effects
    • Extensions

     

    This way, we'll both be contributing to the project and helping visitors on the forum learn more about Inkscape.

    Were you ever able to do a video tutorial? They just revised the logo and the one i have has the same issues as the old one.
