Setting the datum in a tilted coordinate system
After you have positioned the rotary axes, set the datum 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
CfgPresetSettings/chkTiltingAxes
:
„ chkTiltingAxes: On
With an active tilted working plane, the 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 (3D-ROT
menu). If the tilted working plane function is not active, the TNC
checks whether the rotary axes are at 0° (actual positions). If the
positions do not agree, the TNC will display an error message.
„ chkTiltingAxes: Off
The TNC does not check whether the current coordinates of the
rotary axes (actual positions) agree with the tilt angles that you
defined.
Danger of collision!
Always set a reference point in all three reference axes.
