The latest software (2.4.2) has a variable command
robot.arc_height which the robot uses to calculate how far up the Z axis it should move as it goes from point to point. In the beinning of your protocol you will need to import 'robot' and set the desired arc height ex: robot.arc_height = 10. The API defaults the arc height to 5 millimeters but if you set
robot.arc_height = 10 at the top of the python script, the robot should move an additional 5mm up the Z each time it moves.
