Unresolved Crap result... Please Help !

I have done a lot of "improvement" but things are getting worse and worse.
I have upgrader Slic3r to the latest version.

I have modified the ooze parameter, the temperature, etc but the result is bad. It is Robo3D pink PLA and it is warping.

Here is my config :

I would appreciate your help, I'm lost !

 

never done anything on the nozzle.
how do you clean it ?

 

thanks Mark, I'll try that. Anything on my config that you find odd ?

 

Temp at 180 seems low to me, but that is all I saw looking through the settings. Odd to see the internal stringing though at that temp.
