Robotic arm with stepper motor

Let's Make Robots Beginners

I’m design 5 axis arm robot to

Pick and place
Sorting material
Sorting Color

it’s simulate the Sorting production line in factories and i need to make it do it repeatedly.
i’m using Stepper Motor For the Joints of the arm the questions is do i need only Limit switch to each joint cause when the arm starting going to The Home Position and start their movements automatically, or i need encoder or pots in each joint with the limit switches to do this?

You can Add encoders to each joint for real-time feedback and reliable operation over long periods. Avoid relying solely on limit switches if the application involves high loads or complex trajectories. Stepper motors can lose steps under such conditions.
