Well thank you guys, the problem was with my retraction as Illuminarti said, seems the retraction was skipping and then extruding a retracted amount plus the backlog from the skipped layer.Printing sweet as a nut right now.
just printing a new fan head i designed at.24 layer height so we will see how it manages that, but I have printed a couple of test heads and hands and Im certainly getting the same quality Kisslicer was giving ...very happy :-P
BTW i was originally retracting 4mm at 21mm/s had to bring this down to 2mm at 16mm/s ...shocking
