GCODE Printing
Now to print your GCODE, proceed as explained in the paragraph
”PRINTING A TEST PIECE”
.
Overhang and generation of support material
Overhang is the term used to describe those portions of model that cannot be printed using the FFF printing
process without the help of suitable support underneath.
The FFF technology, in fact, assumes that layers will be deposited successively, one on top of the other. The
presumption is therefore that every layer has a supporting layer underneath.
If your 3D model has planes or surfaces that rise upwards from the bottom with a tilt in excess of about 50°
with respect to the vertical plane (40° from the surface), the layer deposited may not have a suitable support
surface underneath, and may therefore cede compromising the quality of the printed work piece.
To avoid problems related to overhang, the slicing software automatically generates material supports
whenever necessary (based on user-configurable parameters).
This additional material must therefore be removed manually after printing is terminated.
Suspending and interrupting printing
Using the menu you can suspend or cancel printing after it has been launched.
To suspend printing, press the jog dialer and enter the menu. Rotate the dialer to the Pause print command
then press to confirm.
Printing will be suspended and on the menu Start page the Pause print status is displayed.
