Use filament color that differs from your build plate color, 0.4 mm nozzle and 0.2 mm layer height!
The smaller gaps between adjacent lines are 0.4 mm wide. If the gaps between adjacent lines come narrower, or there are no gap at all, your bed is too close to nozzle. If the filament is not adhering to bed, or lines look very high, your bed is too far from nozzle.
More orange color means nozzle is far from bed, and when you see more build plate color the nozzle is closer to bed.
