paper). Be careful to only make small adjustments to this setting. Each layer of
your part is usually only around 0.2mm thick, so a small adjustment goes a long
way.
2.3 First layer is printing too fast
As you extrude the first layer of plastic, you want the plastic can properly
bond to the surface of build platform before starting the next layer. If you print the
first layer too fast, the plastic may not have time to bond to the build platform. For
this reason, it is typically very useful to print the first layer at a slower speed so
that the plastic has time to bond to the bed. Cura provides a setting for this exact
feature. If you click on “Advanced” and go to the Speed tab, you will see a setting
labeled “Bottom Layer Speed”. For example, if you set a first layer speed of 20,
it means that your first layer will print 20mm/s. If you feel that your printer is
moving too fast on the first layer, try reducing this setting.
2.4 Temperature or cooling settings
Plastic tends to shrink when its temperature is down. To provide a useful
example, imagine a 100mm wide part that is being printed with ABS plastic. If the
extruder was printing this plastic at 230 degrees Celsius, but it was being
deposited onto a cold build platform, it is likely that the plastic would quickly cool
down after leaving the hot nozzle. Anet3D printer also includes cooling fans that
speed up this cooling process when they are being used. If this ABS part cooled
down to a room temperature of 30℃, the 100mm wide part would shrink by almost
1.5mm.Unfortunately, the build platform on your printer is not going to shrink this
