I’m a noob, so pardon the simplicity of my question. I searched the forums to no avail. I would like to drive a motor with an attached pulley, which in turn pulls a cable. I believe that I should be using a stepper motor, correct? And second, it there a way to either set a hard stop on the motor (so that it doesn’t pull the cable too much or release too much), or to have it stop on resistance?

Don’t know. It depends on what you are using it for…

Yes, but it depends on how fast that motor is turning. And you can’t go from turning to a dead stop without breaking something. But you can get it to slow down reasonably fast.
Also, by “hard stop” I mean not turn any further, not quickly come to a stop.

I described what I wanted to use it for. Right?
Not really. What level of load will be pulled ? How quickly must it be pulled ? Are there any requirements for how much acceleration can (?must?) be allowed ? These questions pertain to the torque and speed, and thus type, of the motor. Do you need to position the object on the cable at specific positions ? Does the motor and pulley have to reverse ? Does the system need a brake (of some sort) to hold the cable from reversing under load ?wolftiger:

Giving “us” more details allows better answers. There are many ways to accomplish what you’ve stated so far. Which is best (if any) is not at all clear. Not everyone wants to play the 20 Questions game. But, by all means, have it your way.
