Backlash
Backlash is a small amount of play between the rotary or angle
encoder and the table that occurs when the traverse direction is
reversed. If the rotary axes have backlash outside of the control loop,
for example because the angle measurement is made with the motor
encoder, this can result in significant error during tilting.
With input parameter Q432, you can activate backlash measurement.
Enter an angle that the TNC uses as traversing angle. The cycle will
then carry out two measurements per rotary axis. If you take over the
angle value 0, the TNC will not measure any backlash.
The TNC does not perform an automatic backlash
compensation.
If the measuring circle radius is < 1 mm, the TNC does not
calculate the backlash. The larger the measuring circle
radius, the more accurately the TNC can determine the
rotary axis backlash (see also "Log function" on page 479).
Backlash measurement is not possible if machine
parameter MP6602 is set or if the axis is a Hirth axis.

Questions and answers
Can I change the approach direction when cycle def a stud to avoid obstruction to the right
The provided context does not explicitly mention changing the approach direction to avoid obstruction. However, it describes selecting different axis configurations using the MOD function in the Programming and Editing mode. If modifying the axis configuration allows for adjusting the approach direction, it may be possible. Otherwise, specific cycle parameters should be checked in the programming manual.
