Manual Leveling

Manual leveling is a procedure that is used to restore the flatness of the print bed relative to the printer reference.

Leveling is part of the machine’s calibration values, and the right value is essential for smooth operation.

This value is automatically saved by the machine during self-calibration.

On machines that are not compatible with the self-calibration system, it is necessary to use the Change Height procedure before leveling the table, in order to obtain a correct calibration.

When a plane is not leveled correctly, there are several problems, as shown in the figure.
This can cause detachment in parts where the printer reference is higher than the real one, and collisions where the printer reference is lower than the real one.

The leveling of the plate is based on the Cartesian principle of the plane passing through three points.

As you can see in the figure, there are three adjustment points arranged around the plate according to the vertices of an equilateral triangle (POSITION 1,2,3
)By properly adjusting each of these points with respect to the printer’s reference (physically represented by the nozzle) you get the correct flatness for printing.
There is also a fourth central position (POSITION 0) that is not adjustable but sensitive to other adjustments. It is useful during the leveling process
