Start, Inserting and Managing of CNC Programs
The CNC-Editor is to be started in the ‚Resources’ tab in the Object Organizer. A tripartite window will
open, the title is 'CNC program list'. In the left column there is a list of the existing programs. The
upper right window part serves as a text editor, where the CNC program can be written according to
DIN66025. In the lower right part the program will be displayed graphically and finally you can modify
the program it in the text or in the graphic part. In each case it will be updated automatically in the
other part.
In the menu bar the item 'Insert' will be replaced by 'CNC program' as long as the CNC-Editor is
active.
Insert a new CNC program:
Set the cursor to the CNC program list and choose command 'New CNC program' in the menu 'CNC
program' or in the context menu. A dialog will open where the name for the new program will be
defined. By default the CNC programs get the name "_CNC<n>", where n is a running number,
starting with "1". You can edit the default name in the dialog, but you cannot use an already existing
name. After having closed the dialog with OK the new program name will appear (shaded) in the list.
In the text editor the first program line is displayed: "% comment", the graphic editor still is empty.
The currently selected program can be edited in the Text editor as well as in the Graphic Editor.
