When printing, watch out how the little holes are printet. They are the first indicators if anything is amiss. The lines itself should have already agood stick. The surface of the squares is annother indicator, if it consists of seperate strings the nozzle is significantly too far from the bed, if it is roughed up the nozzle is too close.
