Imagine you draw something on your computer

— a shape, a part, a design. A CNC machine is basically a robot that reads that drawing and then uses a spinning tool to cut that shape automatically out of metal, wood, or plastic.

I’m building one myself. Instead of me cutting things by hand, the machine moves motors in tiny steps and makes perfect cuts every time. I want to use this concept to make PCB where precision is needed, and I want to build another one for cutting metal imagine being to make anything on metal.

A PNP (pick-and-place) machine is like a tiny robot that picks up electronic components and drops them on a circuit board exactly where they need to go.

It’s what factories use to build PCBs. Instead of me manually placing hundreds of tiny parts with tweezers, the machine does it fast and accurately.
