Selecting and saving machining positions
You must use the touchpad on the TNC keyboard or a
mouse attached via the USB port in order to select a
machining position.
If the positions to be selected are very close to one
another, use the zoom function.
If required, configure the basic settings so that the
TNC shows the tool paths, See "Basic settings",
page 246.
Three possibilities are available in the pattern generator for defining
machining positions:
Single selection: You select the desired machining position
through individual mouse clicks (See "Single selection",
page 256)
Rapid selection of hole positions with the mouse area: By
dragging the mouse to define an area, you can select all the
hole positions within it (Rapid selection of hole positions with
the mouse area).
Rapid selection of hole positions by entering a diameter: By
entering a hole diameter, you can select all hole positions with
that diameter in the DXF file (Rapid selection of hole positions
by entering a diameter).
