Fusion 360, bit travel accross the model

I’m using 3d parallel in fusion 360 and I have an issue about bit travel form start poiint(Zero) and where the bit is supposed to enter in the stock. For now, it’s going straight into the stock to the entrey point and do not travel above stock material to the entry point.
When the job is done the bit travel straight accros the model to the start point.
Any idea about my problem?

Thanks Robert,
I always raise the bit before sending the gcode.
The problem was a parameter in the postprocess in Fusion 360.
