They're very sensitive, the tiniest little nudge will make a big difference! No surprise it freaked a bit. smile
Glad to hear it's sorted, keep an eye out in case it needs another slight adjustment in the future.

Not sure exactly what i did, just spun a little metal piece clockwise and then my printer started freaking out so i unplugged it and spun it the other way a little so I'm honestly not sure what i did but it worked. As you guys can probably tell I'm not great with the hardware side of electronics.

did you raise vref as suggested? over time the trimpots do move a bit due to heating and cooling. it probably needs just a tiny nudge to the right.

^What he said...

EDIT: Vref potentiometer looks something like this:

Also, you may want to check the set screws in the Y drive pulleys to make sure they're tightened as well as the tension of the belts...

Heres a video of what its doing.[https://www.youtube.com/watch?v=DvH_3V94RnE]

A fan on the control board will help if you don't already have one.
Start with calibrating E: steps per mm and extrusion multiplier.  Both are covered in the WIKI.

It will always go backwards until it hits the stopper and continues to kinda just freak out (not sure the terminology XD). I have already done the entire y axis realignment a few times and I get perfect circles just like i should but I can't get it to stay aligned. It looks like the print pauses for a split second then continues all of a sudden in a different spot on the y axis towards the back. ABS does this worse than when i print in PLA.
