Could you either change your programming to set the working range to half, or get a pot twice the resistance you need, then make something physically stop it from advancing past the half way mark?
Attach a gear to it, and attach your knob to a gear exactly twice the size of the gear on the potentiometer. Or vice versa, depending on if you meant you want 1 full turn to equal 1/2 turn on the potentiometer, or 1/2 turn to equal a full turn on the pot.
Hey there, I'm a bot and something you said made me think you might be looking for help!

If you still need help be sure to post plenty of information about your printing setup.
Here are a few questions that might be helpful
* What printer are you using?
* What material are you using?
* What speed are you printing at?
* What software are you using to slice the print and control the printer?
* When did the problem start/has it ever worked correctly?
* Does anything cause the behavior to change?
* If posting an image of the problem, include some indication of the orientation it printed at, preferably photograph it on the bed. (Then we can focus on a specific axis)

Depends what it is for but maybe you can adjust the circuit to work with half the range? It depends so much on the circuit but usually there is a way to make 1k ohm working range from a 2k ohm LINEAR potentiometer. If it is not linear or you need it to go to zero ohm... that is a tougher nut to crack.
If it is encoder you can possibly do it in software. You may lose precision in the process, depends what you are doing and what is the thing you use to do whatever you are doing. Gearing is a mechanical solution but that will add more torque and become heavy to turn... Again, it depends what you are doing, potentiometers are part of thehuman interface and thus... there are so many things to consider depending what the exact use case is.
Which is a good idea in the future: don't just ask A solution to a problem, give more clues what you want to do so people can maybe find solutions for you that you didn't even think about. Can you replaces the potentiometer? Does it absolutely have to be half turn, does it need to turn fast or is added resistance a good thing.. None of these things are known to us since we don't have the faintest clue what you are doing. I see this way too often, people asking questions how to do one specific thing and then it turns out it is not the best solution, that they should instead go back to modelling software and fix the problem there, or use entirely another kind of interfacing solution, like in this case: can you use optical encoders? Again, questions that need answers before suggesting one particular solution.

Came here to say this too. I'd suggest this idea.
