These variables are read-only (R) Synchronous and are evaluated during block preparation.
Here are some examples where the starting point is X0 Y0.
Being function G265 active, the CNC recalculates the center if the arc is not exact but it is within
tolerance.
Being function G264 active, if the arc is not exact, but it is within tolerances, it executes an arc with
the radius calculated from the starting point. It keeps its center.
These variables are read-only (R) Synchronous and are evaluated during block preparation.
(V.)[n].G.MIRROR The least significant bits are used, one per axis (1= active and 0=not active).
The least significant bit is for the first axis, the next one for the second axis and so on.
