I was in the middle of 22 hour build when 2 different times the print stopped. 1st time the filament roll got tangled up. As a result there was too much tension on the line and it stopped. The second time it stopped was when a small corner of the build separated from the build plate. The tip was interfering with the print so it shut down. So what would be nice is if the machine could send to my phone some sort of notification that the build has been paused.
