Here is my final print,
10% infill 0.3 layer
100mm/s retract speed
3mm retract lenght
couldt be more happy with the result 
In addition to that I added a servo for auto bed leveling 
work quite nice I must say but problem is the servo is to far out to the front, I will need to print a new x-carriage so I can put the servo to the side so it can cover a lot more bed surface
