Printing issues

[Audi]

The tower no stringing. Great. Only small nubbs as you can see in the picutre on the tower. But i think i can iliminate them if i turn of the feeding 0,1mm before movement. You can not feel them with your fingers. I did the cube also. I was great. The only thing with cube is on the corners it makes it a bit like zit. So if you measure on the corners its bigger. The size on the cube is 19,80 mm exept if i measure the jight on it. Then it is 20,35mm.Then i tried the multi 3D testprint with many difficult parts in it.Got problems from the start as you can see. It did not stick on one corner. And it looks really wrong the first layer.Is there something wrong with my first layer height or settings in S3D ? I tried the default settings in S3D on all items. No top lid or door.190CBed:50As on the advice on the filament.0,15mm per layerFirst layerLayer height - 100%Layer width - 100%Layer speed - 50%
