Inconsistent filament flow on anet a8 My Anet A8 was working and printing great until my hotbed connector snapped and shorted out my motherboard. After replacing the connections to my hotbed and my motherboard I can't print anything because the filament flow is very inconsistent. It often laying down nothing. See my included picture. 

I've tried a bunch of suggested calibration settings but none of them worked:


increased extruder temp, 
decreased speed, 
increased flow, 


Any ideas or thoughts would be great.
Thanks everyone for the tips. I posted this question on another board and it was suggested my extruder was clogged. After unclogging everything works great again.
