I have a question about 3D ... Arduino-powered control unit and pre-built cameras. Here in 2021, the project works with an even simpler set of items: Raspberry Pi and a Raspberry Pi Camera Module.

There are some exceptions, but most 3D printers run on either an 8-bit Arduino or some Arduino variant ... It isn’t uncommon to see a Raspberry Pi connected to a printer, too, but — again, ...

The Raspberry Pi is all the rage for hobbyists in search of cheap, credit card-sized computers that can run a full PC operating system. Arduino boards ... with models selling for $25 or $35.
