My mistake. That is to be expected. I end my jobs at Z positive steppers stay powered (with a pause at the end so they do not power off), to clear the workpiece and have a gcode saved on the card called “park”. It homes to ZMAX, Then X and Y, after that it drives down to Z min and powers down. So it is parking the head at Z min and it has no dropping left to do. You can do all that in your ending G code, but I prefer to have the safety of my working coordinates being saved in case I made a mistake and need to rework anything on a project and gives me time to clear the parking spot if needed.
