Print problem puzzle

so this started to happen to my ABS prints. At first I thought it was the simplify 3d 4.0 but I uninstall and reset all the settings, chase down all the files and erase them. but nothing.
I am using the latest GB3+ fff file. I have tried a couple old 3= ff files but nothing.

I have taken apart the extruder and cleaned it, I have changed my nozzle. also changed filament and tried different temperatures and adjusted my Z axis. Also I played with the tension on the head. Also I have the door to the electric box open so it can vent better


I am overlooking something...any ideas?


maybe my controller is going bad?
