As there is quite some interest in buying a controller, please contact me via [email protected]. The cost for one controller is currently around 150€ for an assembled + tested version and 90€ for a kit that needs some soldering. Plus shipping from Germany. Unfortunately we're out of stock and due to supplychain issues we are not able to get new controllers before january 2023. But you can, of course, try to order the parts on your own! (please see https://hackaday.io/project/187187/components)

Ethersweep offers easy interfacing from computers/machines/backends to motion control. Every UDP supporting language is able to communicate with it and is able to control as many motors (on your network) as you like.

It gets an IP address from a DHCP server and shows data like IP, operating voltage, button and operation states on the OLED display.

Every motor has to be connected to an Ethernet network (optimally with DHCP) and a power supply between 5.5...30V.

• W5500 Ethernet controller
• AtMega328 Microcontroller (with Arduino Bootloader)
• Trinamic TMC2208 Stepper motor driver
• AS5600 magnetic rotary encoder
• XT30 power connector
• Oled 128x32 Display
• USB / ISP programmable
• Inputs for E-Stop and End-Stop
• Reset button
• Motor current setting via potentiometer
• Fits on a NEMA17 stepper motor

Build an (or multiple) Ethersweep controller. All manufacturing/assembly files work with JLCPCB and only some easy THT soldering + ICSP programming when the boards arrive. Arduino code is available in repository.

Connect your Ethersweep controller to your network via ethernet and connect to a 5.5...30V power source. Stick an encoder magnet (radial magnetized) on a NEMA17 motor shaft and connect the controller to the four M3 screws of the motor. Once connected to power and Ethernet, it serarches for an IP address using DHCP. When an IP is found, the controller shows it on the display and its ready to use. When no IP is found, it defaults to 192.168.1.111.

Now you can use the Python script to control the motor.

import socket
import json

IP_MOTOR = "192.168.1.185" #local motor controller IP
UDP_PORT = 8888


def drive_motor(steps, speed, direction, stepmode, motor_ip):
    json_data = json.dumps({'steps': steps, 'speed': speed, 'direction': direction, 'stepmode': stepmode})
    message = json_data.encode()
    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    sock.sendto(message, (motor_ip, UDP_PORT))


drive_motor(100, 9500, 1, 32, IP_MOTOR)
