Basic settings
The third soft-key row has various possibilities for settings:
Setting Soft key
Show/hide rulers: The TNC shows the rulers at the
left and top edges of the drawing. The values shown
on the ruler are based on the drawing datum.
Show/hide status bar: The TNC shows the status
bar at the bottom edge of the drawing. The
following information is shown in the status bar:
„ Active unit of measurement (MM or INCH)
„ X and Y coordinates of the current mouse position
„ In the SELECT CONTOUR mode, the TNC shows
whether the selected contour is open (open
contour)
or closed (closed contour).
Unit of Measure MM/INCH: Enter the unit of
measurement of the DXF file. The TNC then outputs
the contour program in this unit of measurement.
Set Tolerance: The tolerance specifies how far apart
neighboring contour elements may be from each
other. You can use the tolerance to compensate for
inaccuracies that occurred when the drawing was
made. The default setting depends on the extent of
the entire DXF file.
