I've been opting to go with an arduino with motor shield as the controller. I had planned on setting up the motor and designating the "zero" point to base the steps off of after since I didn't plan on moving the gear position after. It would still be smart to go with limit switches as a failsafe...

That is to be my new problem because with the stepper motor I hadn't planned to use limit switches and base my code off of step counts to provide limits that way. I know I will have to add in limit switches now yes (not quite sure how or best options yet). I had less experience with limit...

I came upon the idea of replacing a stepper and gear reduction with a worm gear motor. I know with worm gears you can't drive the input with the output technically so with my output being the force from the upright screen, would I then be safe in finding a worm gear motor that has a torque...

Is a motor's "self-braking" torque a factor of holding torque or is it variable based on motor design/application. When looking at most stepper motors holding torque is typically the only torque value given. Otherwise the specifications are just electrical and physical sizes. Thanks for the...

I'm trying to determine how powerful of a stepper motor I need for a project. I am attempting to take a display that weighs 15lbs and transition it from laying flat to inclined (approximately 45 degrees) using a stepper motor. I had considered a linear actuator since it would have been an easier...
