In factory each device is subject to the procedure of scanning the table. To provide the optimum print quality it is recommended to
repeat the procedure every several hundred hours of printer operation. It is also recommended to repeat the scanning procedure
in case of encountering problems with print adhesion to the working table or uneven material application by the printer while
printing the rst layers.
The 3DGence INDUSTRY printer is tted with advanced autocalibration algorithm and bed autocompensation. To provide a proper
autocompensation operation it is necessary to perform table scanning. Below we described the principle of operation for the
procedure.
The autocalibration of the bed consists in automatic measurement of the printing bed surface in about 200 points with a pressure
sensor integrated into the printing module. Based on the measurement a virtual table curve map is created that makes up a
base for autocalibration and autocompensation. It is saved in the printer memory and is subject to change only after a complete
working scan is performed (g. 38).
Autocompensation of the bed consists in single-point measurement of the distance to bed and determining a correct distance to
start a job. This process is performed each time before printing. After setting a correct height over a single point, further print will
be performed by taking into account the table curve pattern – thanks to this the distance between the nozzle and the working
table is always the same and controlled in Z axis on a continuous basis.
