Setting a datum in a tilted coordinate system

After you have positioned the rotary axes, set the preset in the

same manner as for a non-tilted system. The behavior of the TNC

during datum setting depends on the setting in machine parameter

chkTiltingAxes (no. 204601):

chkTiltingAxes: On

TNC checks during datum setting 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 Tilt working

plane function is not active, the TNC checks whether the

rotary axes are at 0° (actual positions). If the positions do not

reconcile, then the TNC issues an error message.
