Surface finish on flat figure has pits

[airscapes]

I have attached 3 more models one for .2mm layer .25 and 3mm layer height. These are single layers to check starting height and extrusion multiplier. Once you get a good 2 walled square print the corresponding single layer square. all thread should be well attached to each other and thickness measured with caliper should be that of a single layer assuming you have first layer set to 100% and S3D did not mess up that setting totally..
