Layers not bonding part way through a print
The images probably describe it better than I can, but recently I've been having a problem where the print will be fine, and then suddenly (usually around 12 hours in) the layer adhesion will fail. There are no layer shifts - the layers just stop sticking together.
Any ideas what would be causing this?

Some more info:
[*] printing in PLA.
[*] Same gcode has done this twice at different points in the print
[*] Ambient temperature could be dropping overnight
[*] print settings are default PLA settings for i3mk2

Underextrusion.
Either your filament got snagged, or your stepper driver overheated.

Or:
The hob pulley is loose from the stepper motor
or
You have a clog in your extruder
or
The tension is set too tight on your extruder
or
bad extruder calibration
