hello I want to stop 20 steps forward then 20 steps back and stop it completely after 10 attempts to prevent it from vibrating when the stepper motor rotates while it is exposed to any jams. I would be happy if you help
Post your code (use code tags)
Post a link to the motor, motor driver and power supply.
Post a wiring diagram (pencil, paper and camera work well for this)
Optionally, post a pic of your project to let us see how you have it wired.
You can also correct your writing errors. Then you can tell us what kind of problems you run into.

There seem to be two separate issues here - {A} the code to make it move as described and {B} the question of what causes jams and exactly what you mean by "jam".
For the first, please post the program that represents your best attempt and tell us in detail what it actually does and what you want it to do that is different. It will make it much easier to focus on the parts you need help with rather than wasting time on things that you can do.
For the latter, my guess is that you are describing the situation where the load is too great and the stepper motor is missing steps. That can happen if you are trying to make the motor move too quickly. If working at a lower speed does not solve the problem then you probably need a more powerful motor.
Go get the AccelStepper library and checkout the examples and read the docs....
