Was running this 36hr print, everything was good until I woke up this morning. Have no idea what could have caused the adhesion issue. Unfortunately I also ran out of memory on my SD card so i cant look at the video. This is my thrid attempt at this print and the deadline is coming up so any help is greatly appreciated.
Print was firmly attached to the bed still.
The issue didn't come up from any support weaknesses.
It looks like there was some expansion on the bottom of the part that failed. Maybe this warped somehow. Seems strange though because the top of the existing is near perfect.
Please ask any questions happy to answer.
