GCODE printing
To continue with printing your GCODE, proceed as explained in the paragraph on printing the test piece,
that is:
1. Insert the SD CARD supplied in the package into the slot on the printer front
2. Select the SD Card menu to access the file manager.
3. Select the file to print by turning the jog dialer then press to confirm
4. The machine now starts the automatic printing procedure reading the GCODE indicated and executing all
the phases. You can follow the process from the Info menu or, of course, observing it through the
transparent glass of the machine.
Overhang and generating supports
Portions of a model that cannot be printed using the FFF printing process without adequate supports underneath
are defined as overhang.
As in FFF technology layers are deposited one on top of the other, each layer must have underneath an adequate
support base.
If your 3D model has planes or surfaces that rise upwards with an inclination of over about 50° with respect to
the vertical (40° from the table), the layer deposited may not have sufficient support underneath and may collapse
downwards, compromising the printing quality.
To avoid the overhang problem, and when required, the slicing software can automatically generate material
supports (based on parameters that can be set by the user).
This additional material must therefore be removed manually at the end of printing process.
Printing using two extruders
To print using both Olivetti S2 extruders, the first thing to do is check that the second extruder is calibrated
correctly with respect to the first extruder following the procedures in the section on printer preparation.
Next generate a GCODE file starting from your STL file after having set all the slicing SW options to take into
account use of the second extruder.
