I have seen it some time ago, for the life of me cannot remember where but…
There was an option I believe it was klipper but again not sure, Let’s say you were printing 4 towers of some sort but one of them detached from the build plate, There was an option somewhere that you could cancel just that tower and not have to cancel the whole print. the other 3 could continue and just not make the moves over to the failed tower.
Has anyone heard of it or was I dreaming about it?
