G92 X0 Y0 Z0 ; Specifies absolute coordinates.. . . . . . . . . . . . . . . . . . . . . .
The tool is positioned at the start position (X0, Y0, Z0).
N1 G90 G17 G00 G41 D07 X250.0 Y550.0 ; Starts cutter compensation (start–up). The tool is shifted to the
left of the programmed path by the distance specified in D07.
In other words the tool path is shifted by the radius of the tool
(offset mode) because D07 is set to 15 beforehand (the radius of
the tool is 15 mm).
