If the stylus is deflected by a distance greater than the value defined in MP 6330, the blinking error
message "Stylus deflection exceeds max" is output. The maximum permissible deflection for the TM
110 is 4 mm.
MP 6310 defines the mean constant deflection depth during digitising. On standard parts an entry
value of 1 mm has proven to be useful. On parts with sharp changes in directions (steep edges) that
are scanned at high speed the deflection depth must be increased. The probing for can also be
adjusted with the deflection depth (approx. 4 N per mm deflection).
After the "Meander" or "Contour line" cycle has been started, the probe moves at the feed rate
defined in MP6361 to the clearance height, and then in the working plain to the point above the
starting point. It then moves at the feed rate defined in MP6350 to the MIN point. If no touch point
is reached, the probe moves to the first touch point in the direction defined in the cycle at the feed
rate given in MP6350.
MP6360 (probing feed rate) and MP6361 (rapid traverse in the probe cycle) are effective in the
standard touch cycles (Chapter 9.1).
MP6362 makes it possible to automatically reduce the probing feed rate if the ball tip moves too far
from the path.
During contour-line scanning the probe sometimes ends the contour line at a point located near but
not exactly at the starting point. MP6390 defines a target window within which the probe is
considered to have returned to the starting point. The target window is a square. The entry value is
half the length of one side of the square.
