How to use a printer stepper DC motor to make a 'lift' - Motors, Mechanics, Power and CNC - Arduino Forum

Hi. I like to reuse things, and I have a lot of stepper motors taken from old printers. They look good and strong enough to automate a thing like this: It is a method to use upper space to let dressed drying. What puzzles me is that even if I use one or two of the motors, they are 'loose', in the sense that when you stop giving current, the shaft is free to roll, so everything would fall down Do you know any mechanism to avoid this problem? Thanks in advance, Andrea
