Using a 3-D touch probe (option 17)

Introduction

The behavior of the control during preset setting 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 match the
tilt angles that you defined (3D 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 3D 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
