Each device undergoes manufacturer’s default scan of the work table. For ensuring optimal printing quality, it is rec-
ommended to repeat the scan procedure every several hundred working hours of the printer. It is also recommended
to repeat the scan procedure in case of adhesion problems or uneven application of material while printing first layers.
3DGence ONE printer is equipped with advanced algorithms for autocalibration and autocompensation of the work field.
Scanning the table is required for proper autocompensation of printing process.
Autocalibration of work field is based on measurements of extruder’s pressure sensor examining the surface of work
table in approx. 300 points. Based on the obtained measures, the program creates a virtual map of heatbed curvature,
which is the basis for autocalibration and autocompensation of printing process (fig. 38). Table curvature map is stored
in the printer’s memory and can be changed only after the next scanning of the table.
Autocompensation of the work field consists of single point measurement of the distance to the work field and setting the
correct distance for starting printing operation. Autocompensation process is performed each time before printing. After
setting the correct height over the chosen single point, the printing operation is performed pursuant to table curvature
coordinates (curvature map) stored in printer’s memory for the purpose of real time adjustment of nozzle height in Z axis
to maintain the exact same height of the nozzle over any chosen point on the surface of work table.
Autocompensation settings can be changed from „Calibration” menu by selecting „Autocomp. settings” .
Z offset: Manual correction of Z-axis measurement allows adding (or subtracting) a given value to Z axis single point
measure (autocompensation). If Z offset is set to 0.1mm, the initial height of printing will be lifted by this value:
Height of the first layer 0.2 mm + Z-offset: 0.1 mm = actual printing height: 0.3 mm
