ESP32_GRBL_V4.0_PUB

Overview

All codes are based on open source projects in github.

Source code link https://github.com/bdring/Grbl_Esp32

This design mainly takes into account the convenience of replacing the main control and simplifying the design. It directly uses the ESP32 development board (ESP32-DEVKIT-V1) to plug into the motherboard and the driver, which is convenient for DIY and replacement of burned out drivers.

Supports commonly used stepper motor driver modules, such as A4988.

In addition to the general GRBL functions, two additional buttons (MACRO1, MACRO2) are added to execute scripts or Gcode codes in the memory card with one click. MACRO0 corresponds to 0.nc in the memory card, and MACRO1 corresponds to 1.nc in the memory card.
