17.7 Using a 3-D touch probe
Introduction
The behavior of the control during presetting depends on the
setting in the optional machine parameter
chkTiltingAxes
(no. 204601):
chkTiltingAxes: On
With an active tilted working plane, the
control checks during presetting in the X, Y, and Z axes whether
the current coordinates of the rotary axes agree with the tilt
angles that you defined (3-D ROT menu). If the tilted working
plane function is not active, the control checks whether the
rotary axes are at 0° (actual positions). If the positions do not
match, the control issues an error message.
The probing functions
PL
and
ROT
take the current
rotary axes into account, and the probing points are
derived from this position.
chkTiltingAxes: Off
The control does not check whether the
current coordinates of the rotary axes (actual positions) agree
with the tilt angles that you defined.
If the machine parameter has not been set, the control checks as if
chkTiltingAxes: On
were set
Always set a preset in all three principal axes. This
clearly and correctly defines the preset. That way you
also taken into account possible deviations resulting
from the tilting of the axes.
