The Delete duplicates feature removes objects “identical in size, shape, and position” and objects must be “Ungrouped in order to be detected by Delete Duplicates”. Quotations are literal from the LightBurn Documentation.
I just applied the Delete duplicates on a complex design, with parts grouped where I didn’t want it applied. It went into the grouped objects and deleted duplicate lines anyway! Trusting the software to work correctly, I hit Save before verifying in detail and now I’m stuck trying to recover close to 100 deleted duplicates (for which of course there is no way to detect them automatically).
On top of that: why would duplicate lines in different color layers be deleted? Each layer has a function, and lines can overlap intentionally without causing a problem during cutting/engraving.
Who can explain this? Bug or badly documented feature?
Using LightBurn 1.7.04 on Windows 11, with SnapMaker A350T (10W laser, Gcode)
I don’t quite understand your procedure, when I save a file after I delete duplicates, I can still “recover” the deleted duplicates from the “cleaned” file. Only condition is that the file must not have been closed.
Are identical shapes not identical, no matter what layer they are?
To avoid what you want, disable all the layers you don’t want to search for duplicates.
