hello All !! some advice please is needed

if you look at the 5 mm image all seams fine with the project however if I go deeper to 6 mm Laban cnc 3x wants to shave part of the project down to meet the 6 mm request as i try even deeper the shave effect increases ? i also have up loaded the gcode

weather i generate the stl file in blender or Fusion i have the same result

I guess your model is not parallel to the bed but not on the PC right now to verify.
Your model file would help in this case.
Workaround would be to simply mount your workpiece 1mm higher on the bed.
