After you have used the quick selection function to mark hole positions,
a pop-up window appears in which the smallest diameter found is to the
left and the largest diameter to the right. With the buttons just below the
diameter display you can adjust the smallest diameter in the left area and
largest in the right area so that you can load the hole diameters that you
want.
The following buttons are available:
Filter setting of smallest diameter
Display the smallest diameter found (default
setting)
Display the next smaller diameter found
Display the next larger diameter found
Display the largest diameter found. The TNC sets
the filter for the smallest diameter to the value set
for the largest diameter.
