Check the bed is clear of any build material

Ensure that all build material is completely removed from the bed. Use the model removal
tool to remove any stuck-fast tracks.
It is normal for prints to leave marks on the bed, and for the model
removal tool to lightly scratch the surface of the bed. This will not
affect the printer's operation. However, take care to avoid gouging the
surface with the material removal tool – the bed must be flat.
