Cutout Dimension Issues

Hello, today I cut out the facade and at the end of the work it turned out that the size is a little larger than necessary. But the holes for the inserts are in size. In general, I don’t know what to do …the most interesting thing is that the holes for the inserts are in size and the workpiece itself is a little larger


800x400 , and inserts 50 mm

16mm and 11mm are very large errors; too big to be all mechanical. Can you post the gcode you used to cut this? I bet there was an error in the CAM configs.
