Raspberry Pi CNC Hat Controlled CDROM Stepper Motor

Purpose: Learn how simple it is to use the Raspberry Pi CNC Hat from Protoneer by testing it out on a CDROM stepper motor.

Why: Many of us dream of making our own CNC router / engraver but get bogged down in the details and unknowns. This is a simple and inexpensive way to test the waters using components you may already have laying around.

Time: ~2 hours including flashing the SD card & soldering.

Difficulty Level: Beginner
