Using a 3-D touch probe

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.
