Using a 3-D touch probe (option 17)

Introduction
The behavior of the control during presetting depends on the
setting in the optional machine parameter chkTiltingAxes
(no. 204601):
chkTiltingAxes: NoCheck The control does not check whether
the current coordinates of the rotary axes (actual positions)
agree with the tilt angles that you defined.
chkTiltingAxes: CheckIfTilted 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
positions do not match, the control opens the Working plane is
inconsistent menu.
chkTiltingAxes: CheckAlways 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 match.
If the positions do not match, the control opens the Working
plane is inconsistent menu.
Operating notes:
If the checking function is off, the PL and ROT
probing functions use a rotary axis position that is
equal to 0 in their calculations.
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.
The control issues an error message if you do
not use a 3-D touch probe for presetting and the
positions do not match.
If the machine parameter has not been set, the control checks as if
chkTiltingAxes: CheckAlways were set
Behavior with tilted axes
If the positions do not match, the control opens the Working plane
is inconsistent menu.
Soft key Function
In the 3-D ROT menu, the control sets Manual
Operation 3-D ROT to Active. The axes move in
a tilted working plane.
Manual Operation 3-D ROT remains active until
you set it to Inactive.
The control ignores the tilted working plane.
The preset defined applies only to this tilted
condition.
