the abs retract too much

EAC

ive printed some long lined object and the abs retraction make them curve , wich setting in retraction can i use?

Repetier

I don't think retraction curves abs. Abs has big problems with long objects since warping tilts them up in the corner. Google "warping 3d print abs" for more informations about this phenemon. A heated bed, better adhesion to bed and a heated print chamber are things that help here.
