The “beads on a string” aspect of the extrusion suggest a partial nozzle clog? Does your filament feed motor skip every few seconds? In Cura by default the first layer is printed with thicker lines/more extrusion for better adhesion to the print surface, which may explain why the first layer looks different.
Obviously, your print is not sticking well on the bed. [quote=“malwin23”] Noozle is leaving ca 0,35mm of gap[/quote]It’s too much as it’s the diameter of the filament. You should use 0.2mm or even a bit less. If the thread of filament is deposited without being squeezed each line is too thin hence the gaps between the lines.

[quote=“malwin23”]i did 0.176mm outisde shell, wonder how it will work when i multiply it [/quote]You’ll have to test slicing with different thicknesses. The slicer is extruding more or less filament to try to achieve the desired thickness. When squeezing a 0.35mm diameter filament the resulting thickness of the deposited filament should be wider. To avoid this if you asked for a lower thickness the extruder slows down to extrude less filament. So its quite hard to tell the result. My average shell thickness is 0.6. More than 50% infill will extrude too much filament. An interesting parameter is the “Infill overlap” (set it at about 10%). It’s avoiding the gaps between the shell and the infill.

Sorry that i did not reply faster i’m very busy those day ;/ 3 jobs etc hehe I’m doing now even more pefect prints. I tested Your solutions and they are good. Thanks for advices.
But there is one thing what i did… and it’s working perfect. I replaced the nozzle diameters in program data from 0.35 to 0.31. Connections are much better then ever! layers are amazing smooth (when i print using 100% infill for parts for my new printer). And my infill overlap is 5%.
I’m building now my own 3D printer. Below is screenshoot, just a simply construction without other elements :(:
Size of cover is 790x700x1050mm of height. It will be huge print area that I want to get this 450x500x700mm. It will be working at COREXY kinematics. I got aluminium profiles and more parts. Once i update schema with top platform i will send You info.
