Various modes (Q406)
 Test mode Q406 = 0
 The TNC measures the rotary axes in the positions defined and
calculates the static accuracy of the tilting transformation.
 The TNC records the results of a possible position optimization
but does not make any adjustments.
 Position Optimization mode Q406 = 1
 The TNC measures the rotary axes in the positions defined and
calculates the static accuracy of the tilting transformation.
 During this, the TNC tries to change the position of the rotary in
the kinematics model in order to achieve higher accuracy.
 The machine data is adjusted automatically.
 Position and Angle Optimization mode Q406 = 2
 The TNC measures the rotary axes in the positions defined and
calculates the static accuracy of the tilting transformation.
 First the TNC tries to optimize the angular orientation of the rotary
axis by means of compensation (Option #52, KinematicsComp).
 If the TNC succeeded in optimizing the angular orientation, it then
optimizes the position through another measurement series
Example: Angle and position optimization of the
rotary axes after automatic datum setting

For angle optimization, the machine manufacturer must
have adapted the configuration correspondingly. You can
ask your machine manufacturer if this is the case, and
whether an angle optimization makes sense. Angle
optimization can be particularly useful on small, compact
machines.
Angle compensation is only possible with Option #52
KinematicsComp .
