I decided to print default cat gcode, which was in complect with printer, here is what i got:

Lower level was at default 100% flow, after i changed to it to 150% i went pretty good. Then i measured nozzle, cause there was no markings on it, and it probably was 0.4mm.
Then i got cura slicer, set nozzle to 0.4 with 0.1 height and it seems to be printing now, but flow still needs to be set as 150-165.
