problems later on. There are many different ways to cope with these first layer
adhesion problems, so we will examine several typical causes below and explain
how to address each one.
2.1 Build platform is not level
Anet3D printer uses 4 screws to control the position of the bed. If you have
trouble to get your first layer to stick to the bed, the first thing you need to verify
is that your printer’s bed is flat and level. If the bed is not level, one side of your
bed may be too close to the nozzle, while the other side is too far away. Achieving
a perfect first layer requires a level print bed. Anet3D printer already has a useful
bed leveling video that guide you through the bed leveling process.

2.2 Nizzle starts too far away from the bed
Once your bed has been properly leveled, you still need to make sure that
the nozzle is starting at the correct height relative to the build platform. Your goal
is to locate your extruder the perfect distance away from the build plate — not
too far and not too close. For good adhesion to the build plate, you want your
filament to be slightly adhesive against the build plate. You can adjust the four
screws at the corners of the hot bed, turn the screws anticlockwise and the hot
bed will move up. Turn a little once to reduce the distance until there is suitable
room for filament extrusion(The distance is about the thickness of a piece of A4
