oppss.. bro mas taas ug torque ang stepper boss kung low speed but sa high speed mas nindot ang servo kay maka maintain siya sa iyang torque maski taas ang RPM.
"You use a servo motor when you want a very high degree of confidence that the system will closely track what you ask it to do, particularly in high-performance cases. You do not need to spend nearly the time characterizing the system to make sure that it can work under all possible conditions -- you really just need to check the boundary cases."
"you use a stepper motor when you can, to save the cost of the feedback sensor and its processing electronics. You must have high confidence that the motor will hold its desired position no matter what you ask it to do in the application. This is not always easy to ensure, and can take a lot of development time to demonstrate, and it does put outer bounds on your performance."

Stepper vs Servo Motors
if you like we can supply ur custom mechanical parts of that project bro.
