Check the G-code to see what the Z depth is at the last cut. With 9 mm shift, you should be able to roll the preview window until Z is parallel to the screen and see such a Z shift, if it were there.
My guess is the machine is losing steps during many up/down moves, and they are accumulating in the direction of gravitational pull, ie. down. I suspect if you made a program like this : G01 Z0 f25 Z1 Z0 Z1 Z0 Z1 ...... you would find the same drift in the Z=0 position.
