Hairy parts

does somebody know why there is some hair between sommit in my parts ? or more precisely how not to have it ?

i've tried retraction, hotter, cooler, fan , no fan and it's more or less the same

is it a PLA dependant thing or a configuration pb ?

slic3r/pronterface/prusa/ buddaschnozzle 0.5 or 0.25 nozzle/ from 175 to 190°

thank you

after i reflashed firmware i lost this problem also i set retraction to 2mm

already done but no change

i'm beginning to think about the temperature and the need to blow the buddaschnozzle heatsink to avoid too much filament to melt (which could explain the nozzle jamming with melt PLA going upside the limit and cooling in the black plate under the wade extruder)

anyway i'm designing a fork for the 3 LM8UU x carriage with built in support for the buddaschnozzle and a fan for the heat sink and cooling the printed parts

printing "en route"
