G-Code interface
Menu: Icon: Short cut:
Saves layer data in the G-Code file format
In order to directly interface RP-systems using a CNC controller, a programmable G-Code
interface has been integrated for the export of slice data including hatches and supports.
The G-Code file format is mainly used for controlling NC-devices. Therefore it is widely used as
an input to NC device controllers.
To adapt the G-Code output to a certain device controller, you can create user-defined profiles to
specify the layout and content of your own variant of the G-Code file format. Within the profile
you can specify how to map the different vector types (e.g. contour, support, hatch) to certain
G-Code commands, which will then control your NC device. The different vector types are
specified on separate tab pages. Each vector type itself is specified as a G-Code command line
consisting of user defined G-Code commands, pre-defined macros (variables which are replaced
with data later while writing the file) and may comments (optional).
HINT: To open the G-Code interface dialog, the file type "ISO G-Code Postprocessor Format
(ISO)" must be selected in the file manager when saving a slice file.
A G-Code file is structured as shown below:
program start
-----> layer 1 start
-----> contour 1 start
-----> outloop border line 1 to outloop border line N
...
-----> inloop 1 to inloop N
-----> inloop border line 1 to inloop border line N
contour 1 end
...
contour N
...
-----> hatch block 1 start
-----> hatch line 1 to hatch line N
hatch block 1 end
...
hatch block N
...
-----> support block 1 start
-----> support line 1 to support line N
support block 1 end
...
support block N
...
layer 1 end
...
layer N
program end
Wherever necessary, a rapid traverse command line is automatically inserted.
HINT: The block order of supports, borders and hatches can be modified within the dialog Define
machine on the tab page Layer.
