Unresolved Now getting messy printing!

Hello all
i was printing out some nice stuff then one day it started to print sloppy and i don't know why exactly
I am not sure but the i may have accidently messed up the y axis. It Looked like one side was lower than the other so i had adjusted it. it looks even and strait but been having sloppy printing lately. I use ABS
and my temp is like 225-230 for nozzle and my bed at 80
In the image i had printed kylo rens light saber first one came out good and did a black paint coat.
Now when i did the second one like a month later it was printing out sloppy. any reasons why it would do that?
is my bed too loose? or too tight? or the y axis messing it up?

 

Could be over extrusion or fat filament.

 

Either way you definitely have some z artifacts going on. Check and make sure the coupler is not loose.
