3. The print head warms up too slowly and the temperature
fluctuates greatly

The print head is too close to the printing platform, and the cold air
from the cooling fan is blown back to the heated aluminum block,
which causes heat loss and temperature fluctuation. It is
recommended to rise the print head before the print head heats up
to ensure that there is a distance of more than 3cm between the
print head and the platform.
