I tried to use prusasliser, but it doesnt have ender 5 printer settingss on it, and i'm not sure if ender 3 settings will work.
To deal with my flow rate problem i just manually increase flow to 150 before every print, and will it go better if i just download and install official firmware?

Also,
Printing some models: default gcode files, which were on sd card in complect and sliced ones(with cura sliser) i got different results. When i print default model, cat, for example, 1st layers starts to print instantly and seems normal, but when i try to print sliced model, 1st layer is just barely visible on bed and printing starts from layer 2.
But both types had same problem, there are gaps between layers of plastic and infill seems to be deformed:

As a result, top layer goes bad to. These gaps are so wide that i can just move layers.
I have read that putting extruder width less then actual may help and I am gonna try it next time.
