Help me with my first printer ender 5, i'm ready to give up

[curious aardvark]

is that 150% flow ?
that's way too high. Should be mearer 100 - ie somewhere between: 90-110.

best advice is for you to download prusaslicer and try that.

Cura is just way more hassle than it'e worth.
I no longer bother with installin cura on my work computers.
It would be purely for diagnosing other people's problems - and it's just so much quicker to say: use something else :-)

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.
