FluidNC 4x TMC2209 Chips

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.

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.

Features

- (4) TMC2209 Stepper Drivers in UART Mode
- Can use stallguard for sensorless end stops
- (6) inputs
- (2) CNC I/O Module Sockets
