with rotary tables
Use the 3-D touch probe to rotate the coordinate system. See “Touch

Write down the rotation angle and cancel the Basic Rotation.
Select operating mode: Positioning with MDI.
Select the axis of the rotary table, enter the rotation
angle you wrote down previously and set the feed
rate. For example: L C+2.561 F50
Conclude entry.
Press the machine START button: The rotation of the
table corrects the misalignment.
