Overview

This is a 4 Axis CNC controller with (4) built in TMC2209 stepper motor drivers. It is designed for use with FluidNC CNC firmware. The firmware has full control of the motor drivers via UART to set the microstepping, current and other features.. The drivers can be used for a 4 axis machine (XYZA) or they can be doubled up on any axis (XYYZ, XXYY, etc). You can use Stallguard sensorless endstops by directing that signal to limit switch inputs via jumpers.

It also has (2) CNC I/O Module sockets. These allow you many different types devices from spindles, laser, coolant devices, relays, etc. See the list below.

The controller has (6) standard inputs for limit switches, etc. If you need more inputs you can use input modules in the CNC I/O module sockets.

What you get.

You can the basic controller with all mating connectors and hardware. You can optionally include a programmed ESP32 module. The CNC I/O modules are ordered separately.
