I am writing to seek your assistance with an issue I encounter while using LightBurn for a specific workflow.
I use a fiber laser for PCB prototyping. To generate toolpaths from Gerber files, I use FlatCAM software, which outputs vectors in G-code format. I then import this G-code file into LightBurn.
The problem arises when I need to edit these imported vectors. The entire design is imported as a single, grouped object. I need to delete certain specific elements from this vector group, but the “Ungroup” button is greyed out and unavailable. The only workaround I have found is to export the entire design from LightBurn as an AI file and then re-import it. This is quite frustrating and disrupts my workflow.
Could you please advise if there is a way to fix this situation directly within LightBurn? Perhaps a setting upon import or a different method to make these vectors editable would be very helpful.
I believe the solution lies in saving the file to vector format. If the file opens in Lightburn as a single object, it’s because it was saved as a single object and not as multiple grouped objects.
But there are those who are more familiar with this type of occurrence than I am. Stay tuned, other opinions will emerge.
GCode is not a Vector file, it is a programming language for CNC machines. It carries NO design information, and thus you cannot modify it in Lightburn.
@Kuth Gave the right solution. From FlatCAM, save it as an SVG file. IMPORT that into Lightburn, and then save it as a normal Lightburn design file. You now have a file that you can modify, like assign layers and move parts, as needed.
Also, Welcome to the Lightburn Forum. There are thousands of members and Lightburn staff willing to help you succeed with your laser. Just do not be afraid to ask questions.
Thank you for your response. I understand that G-code is not vector-based, but importing it seems like importing a vector. To work around this, I exported the file as an .ai format and re-imported it. By the way, EZCAD allows editing imported G-code, ungrouping the paths. I hope Lightburn will support this feature in the future.
