String, brown paper and g-clamp approach to sending the eMotimo TB3 vertical with a 5:1 stepper motor driven from the 3rd axis.
Speed is approximately 3ft in 17 seconds using a 20 tooth drive pulley in Q configuration. If the trolley and its load are counter balanced correctly then the 5:1 stepper is more than capable of lifting and holding the load.
By tomorrow this unit will be striped down and on its way to be converted to its intended purpose as a trolley / track for a Servocity pan/tilt/roll unit. It weighs in at 30+ lb and is powered with three NEMA 17 0.9 degree stepper motors coupled to precision gearboxes to reduce the effects of backlash so badly exhibited by the usual stepper/gearbox arrangement. The gearbox and pulley drive (600:1) will be capable of 10,667 steps per degree.
