Hello 
I have a ultimaker 2+ with bondtech QR feeder and 3D solex matchless nano kit.
Long belt are new.
All axis is clean.
No hard point on Z screw.
PID tuning done
E-step and flow perfectly calibrate.
With colorfabb white economy PLA (New)
Nozzle 200°/bed 60°

I have a problème with my layer.

Update

I mesured the head temp with my multimeter and type K sensor.
I have a big difference, it's normale ? 

Maybe it's my bad layer problem ?
