1) Accurate leveling
If you level hot bed with A4 paper, the first layer might be too high, too low or moderate.
a. Too high: If the distance between nozzle and hot bed is too far, filament will not stick to the
bed well. See picture (6-5).
b. Too low: If the distance between nozzle and hot bed is too close, it prevents filament from
coming out, causes the extruder gear to click or grind on filament and even worse, it would
scratch nozzle and hot bed. See picture (6-6).
