GRBL for STM32 - NUCLEO

This repo represents the version of GRBL for STM32F411RET6 MCU. This MCU is located on the STM NUCLEO board, picture 1.1. This project can be used with standard GRBL shield like Arduino CNC Shield or three STM shields X-NUCLEO-IHM01A1, for stepper motors. With minor modifications COREXY configuration is also supported.

Why NUCLEO board?

Reasons for choosing open Nucleo environment are:

  • it is cheaper then Arduino UNO
  • better ARM MCU, a possibility for new features
  • open SDK and IDE
