I am making an elevator and the stepper motor is just vibrating when I push the button and it doesn't turn. It used to work, but it suddenly stopped working. What should I do to fix it?
Here lots of info on how to get help solving your stepper problem.
After that, check your wiring, code and power supply, and replace any parts that have released their magic smoke. If that still doesn't work, try following the instructions in the link I just gave.
The link that you provided didn't give any help. I need a way to speed up the stepper motor by changing the code or using a different materials.

the stepper motor .... used to work, but it suddenly stopped working.
...this:

... makes no sense.
The second comment is the sort of thing you would say if it was working, bit not correctly. First comment says it's not working
And it's not clear (to me) what this:
spencerkim:

... means.

It can help you get help. If you provide the information suggested. Which you didn't. So we can't offer help.
spencerkim:

Then something must have changed.
What did you do to it?
Hi,
If you have tried to speed up the stepper and now it doesn't turn, go back to old code where the stepper rotated and check that it did.
OR
When you wrote your code, properly, you must have at some stage written code that JUST runs your stepper, try it.
If you don't have such a code, how did you develop your code?
