Imported SVG File will not show contour or burn/mark

New user here. Running an OMTech Galvo with Raycus source, JCZFiber (USB-Lite) with latest version of Lightburn.


I’ve been successfully engraving steel with text phrases created in Lightburn for a few months. A colleague has created an image to be engraved on metallic coins and saved it as an.svg file. I’m able to import, view, scale and move the image around my workspace. I can also preview/play the burn path. When framing the image on the work piece, the laser will only show the perimeter but not contour the actual image, and when attempting to start the burn, no activity from the laser takes place regardless of speed, frequency, or other settings. If there is a means to upload or email the .svg for your evaluation, please let me know and I’ll do so.

What I’m seeing here is your file is not an SVG, it’s an image file. If it were an SVG it would show the lines. I believe an image file will only trace the outline as it doesn’t have any other lines to trace.

Thanks for quick reply, Tim. The file was sent to me as a .gmail attachment, which I saved to my desktop. The file extension is .svg, but it is also designated as a Microsoft Edge HTML document. Should I try to export the file using different software into a .svg format?

Maybe try opening it in Illustrator or Inkscape?

It’s a simple enough file you could try image trace in Lightburn.

Thanks again, here is how the file properties are displayed in Inkscape

I’ve not yet tried image trace elsewhere, I imagine this is an automated function (you are not manually tracing image with mouse)

No, it’s automated with sliders for adjustment. Here is the doc. for that feature.

I think he imported a graphic and saved it as SVG. I just did a quick test and it’s easy to do. Check in Inkscape if there are any text layers. In this graphic there should be at least 5 distinct text layers. If you can’t get a good trace, I recommend you get him to resend the file in a proper format.

A graphic is a bitmap and an SVG is a vector file. Lightburn apparently recognized it as a bitmap because it was not the SVG format.

Yeah, do what Tim said.

In Inkscape and probably Illustrator as well, I didn’t try there, you can import a bmp graphic and save the file as svg. The bmp will still be a bmp but housed in an svg wrapper. Lightburn correctly imported it as a bmp even though it’s a svg file. (that’s a lot of file extensions in those sentences) :face_exhaling:

I saw this by the fact that the layer was set to image ratherthan a line or fill mode.
