I am looking at your 12V, 2.8A 3333 oz-in NEMA-23 Bipolar Stepper Motor. Could I use this for lifting a point on a platform, where a person could stand on? I would like to use multiple of these motors, let say one for each meter square. The disance between the point still need to be desided. The total plaform will be about 20 meter long and 3 meter wide, where each point indivial will be moved to a certain height to get a ungulating area.
Welcome on the forum.
