Description

ESP32-CNC

ESP32-S3-based CNC/3D printer controller designed to be used with FluidNC.

Features

  • 4 DRV8825 stepper motor drivers capable of up to 2.5A 24V each (with the ability to set the maximum current)
  • 4 high-current MOSFETs, up to 30A at 24V per MOSFET, designed for controlling spindles or hotends
  • 8 switch connections (7 general purpose/limit switches and 1 emergency stop, though this can be used as a general purpose switch too)
  • Ability to configure microstepping using DIP switches
  • 4 WS2812B addressable RGB LEDs for status indication
  • USB-C port
  • Detailed silkscreen

Thank you to OSHWLab Stars for making this project possible.

Note: if you're going to make this project yourself, I'd recommend increasing the resistance of the LED resistor as the LED is a bit bright currently
