I have encountered a problem with Cura 3.6 on Ubuntu.
I have been using it (and previous versions) for over a year and it has been working beautifully.
However, I opened it yesterday and everything works fine until it starts slicing, when it stops (with no messages) about a quarter of the way through. Slicing time stays at 0:00, I can't save the file and it just stays there no matter how long I leave it open. I have attached a screenshot.
I uninstalled Cura, removed all config and related files I could find, reinstalled it and the same thing is happening.
Does anyone have any ideas?
