IMO buying a hackable 3D printer is the best way to get practical experience with kinematics, motors, stepper controllers, etc. The standard recommendation is to buy an Ender 3, but it’s very slow by today’s standards. I’d recommend Flsun V400, it prints almost as fast as the state of the art, but has no proprietary components, and comes (almost) pre-assembled.
