To find an appropriate G199 R value:

  1. In MDI mode, command an M19 to orient the main spindle and an M119 to orient the secondary spindle.

    This establishes the default orientation between the spindles’ home positions.

  2. Add an R value in degrees to the M119 to offset the secondary spindle’s position.
  3. Check the interaction between the chuck jaws. Change the M119 R value to adjust the secondary spindle position until the chuck jaws interact correctly.
  4. Record the correct R value and use it in the G199 blocks in your program.
