I was thinking it could be a problem of settings/printer itself, but in 2 different sizes(240mm and 300mm), there was a crack as visible in photos I've posted(tiny line of something that looks like under extrusion on the height of lips in both prints it was on the same part of the model). I'll try to print it once I am back from holiday :) So probably mid-September. I'll give you feedback for sure! Maybe that's just a problem of upscaling.
