Beschreibung
Zusammenfassung:	The subject of the present invention is a system for self-levelling a table in 3D printers, which comprises a system for moving the table in the Z-axis and a system for detecting the level of the table, characterised in that the system for moving the table in the Z-axis comprises three platforms attached to the table and mounted on three drive screws, each of which is driven by an individual motor, each platform comprising a first element and a second element, a drive screw nut is mounted on the first element, said nut being spherical in shape and seated in a spherical pan, a rod is stalked from the first platform element, moving in a linear bearing embedded in the second platform element so that the second element can rotate and move, said second platform element being fixed to the 3D printer table, preferably from below; and the table level detection system comprises two mirrors, a left mirror and a right mirror embedded in two adjacent corners of the table from below, a laser and a camera d for detecting the unevenness of the table with respect to the machine base.
