Hotend too low
The material is pushed out of the hotend while
printing the rst layer. It leads to deformation of
the base of the printed model. It’s an indication to
recalibrate the heatbed.
Hotend in correct position
The material is laid out regularly. Whole surface of
the model’s base is covered with plastic and the
upper surface of the rst layer is a regular, at and
lithe plane.
Hotend too high
The distance between the heatbed and the hotend
is too large. It causes a poor adhesion of the ma-
terial to the heatbed. It may lead to the model to
be peeled off during printing. It’s an indication to
recalibrate the heatbed.
