help building pi/arduino projet

hi,
i need help to build a bartender with a nema17 stepper motor and a Linear guide and 1 servo.
i already have a idea of how it should work .
i need help to chose the correct components (stepper driver, Arduino or Raspberry pi ect...)
you will have to help me choose the right components and help me write the code for the project to move forward.

i already have:
- arduino uno
- raspberry pi 3/4
- linear guide
- stepper motor
- drivers (TMC2208,DRV8825)
I have a preference for the raspberry pi and python

Maybe only weekend we will be working on this projet, i'm not in a hurry, the goal is to learn at the same time

I speak french and english

if you have any questions, do not hesitate to ask questions in private in order to fully understand my needs
