Before we start to solve this problem we do need to know the diameter of the ball screw thread and the weight of the 800 watt unit along with the stepper motor used.
It does sound like the stepper is too small and the forward weight of the unit is over powering the holding torque of the stepper.
But mate a picture says a 1,000 words so put one up so we can have a look and we can go from there.
