The Raspberry Pi in ... building block for robotic and CNC applications. [Alpha le ciel] is building this stepper motor module as the first of many Raspberry Pi hats meant to provide the Raspi ...

Started this project to convert my Sieg micro milling machine to a cnc machine. The idea was to use a raspberry pi as the controller, using its GPIO, so no (8bits) microcontroller involved. A full pc ...

Turn it over and you’ll find a Raspberry Pi 3 and a CNC hat. The knobs are belt-driven from a pair of NEMA-17 size stepper motors that interface to the knobs with tight-fitting pulleys.

The display attaches to a Pi via the GPIO. It is a 128x64 1.3" blue OLED display with a 5-way joystick on one side, and 3 buttons on the other: Driver: SH1106 Interface: 4-wire SPI, 3-wire SPI, I2C ...
