I'm relatively new to Cura, having just installed it a few weeks ago. I have 3.0.3 and I'm running on Windows 7 64 bit. I noticed the auto slicing setting while poking around the settings. Auto slice almost always works.
A couple times now, Cura won't auto slice. I can't seem to find the slice button. How do I manually slice? I found an article on how to disable auto slicing, but it doesn't show how to manually slice.
Where the button "save to file" is is greyed out and just says "Print with Octoprint".
Closing Cura and re-opening it will fix the issue.
