Filament/Adhesion Problems?

I set up myprinter and made a couple things, no problems. I left my printer running and went to bed. Woke up to a mess, part was pushed around, stingy abs everywhere. Now when I print I get missing rows of infill, the skirt prints no problem. Here's a pic to describe it. Haven't changed any settings. Pic is off my phone, hope it works.

here are a few things to check.

1. check that your hobbled bolt or gear (that pulls the filament in) is not clogged up with filament (in between the teeth can get filled in thus it can't push filament through well).

2. Check to see if your nozzle is partially jammed with debris, might have burned plastic or junk in it not allowing proper flow.
