First fail was open 3 months in dry room. second was brand new, Less than 2 minutes out of sealed pack when print started, same fail, just didn't adhere, roughly 14 hours into print.
Can't afford the waste & mess of prints that fail at 3am! Ain't staying up all night watching the feed with my finger on the pause button for each test.
Given it was NOT damp filament, I don't know what to try tweaking first; extruder temp ? flow rate ? Fans?
Sounds like you need to dry your PVA... Its very sensitive to moisture..
Pictures of the print failure would also help
