In the present layout, the tool position $AC_MEAS_TOOL_MASK and approach direction to
the workpiece $AC_MEAS_DIR_APPROACH must be set as follows:
Left-hand tool: Approach direction and tool orientation +x
System variable Meaning
$AC_MEAS_TOOL_MASK = 0x2 Tool position in x direction (G19)
$AC_MEAS_DIR_APPROACH = 0 Approach direction +x
Right-hand tool: Approach direction and tool orientation -x
$AC_MEAS_TOOL_MASK = 0x40 Tool position in the -x direction
$AC_MEAS_DIR_APPROACH = 1 Approach direction -x
For both tools
$AC_MEAS_Px_COORD = 1 Coordinate system of x-th measuring point = BCS
$AC_MEAS_SET_COORD = 1 Coordinate system of the setpoint = BCS
