So I was just re-working a design based off of a previously saved file with existing toolpaths.
Deleted all the vectors I wasn’t using & assigned some new toolaths vectors.
Upon doing a simulation, an Engraving toolpath which shows as Empty in the toolpaths list continues to work with the old vectors which no longer exist. The toolpath settings also show zero vectors selected.
Ghost toolpaths!
Anyway, just a weird bug which I don’t believe I’ve encountered before.
Once I assigned some other vectors to the Engraving Toolpath, it seemed to finally clear out the old toolpaths.
I also tried saving the file with the ghost toolpaths, then closed & re-loaded the file - the ghost toolpaths were gone. So maybe it was just a weird little memory glitch.
