Overview

This is a small and simple CNC controller for your laser, pen plotter, sand plotter, etc. It runs FluidNC firmware on a ESP32 controller. It can be controlled via USB, WiFi or Bluetooth via PC, phone or tablet. It uses TMC2130 drivers with full firmware control of all features including StallGuard sensorless endstops.

• This does not include the motor driver modules. I recommend the BigTreeTech brand, TMC2130 V3.0 or TMC5160 V1.3
• The ESP32 module is optional. If you buy it from me I will custom program it for your machine.

Features

• ESP32 Socket for standard ESP32-DevkitC module.
• Micro SD card socket.
