Element information
At the bottom left of the screen, the TNC shows how far the
reference point you haven chosen is located from the drawing
datum.
Selecting and saving a contour
You must use the touchpad on the TNC keyboard or a
mouse attached via the USB port in order to select a
contour.
Specify the direction of rotation during contour
selection so that it matches the desired machining
direction.
Select the first contour element such that approach
without collision is possible.
If the contour elements are very close to one
another, use the zoom function.
