The WiFi Stepper is a powerful and versatile wifi-connected stepper motor controller that can support a single stepper motor of up to 85 volts at 10 amperes. Today I’ll show you how to use this device along with its web-based user interface to perform all sorts of tricks with a NEMA 17 stepper motor.nnArticle for this video at dbot.ws/wifistepnMore Articles and tutorials at dronebotborkshop.comnnWiFi Stepper on Crowd Supply - www.crowdsupply.com/good-robotics/wi-fi-steppernnGet the newsletter and let me know what videos and articles I can make for you - dbot.ws/dbnewsnnToday I’m testing a very interesting piece of technology which was sent to me by its creator, Andrew Klofas of Good Robotics. It’s a wifi-controlled stepper motor controller with some very impressive capabilities and specifications.nnAndrew is crowdfunding this project on Crowd Supply - www.crowdsupply.com/good-robotics/wi-fi-stepper. nnThe device, as its name would imply, will allow you to control a stepper motor over wifi. It will support both very small and very large stepper motors, anything up to 85 volts at 10 amps!nnI tested it with a 12-volt NEMA 17 type stepper motor and it performed very well. The web-based interface allowed mt to control=virtuially every aspect of the stepper, and it even allowed me to operate it in “Servo Mode”, giving my stepper motor “servo-like” behavior.nnThe board makes use of four main components:nnESP8266 WiFi controller.npowerSTEP01 stepper motor driver.nMicrochip ATECC508A crypto-authentication module.nMaxim MAX15062 high-efficiency voltage regulator.nnTogether these work with a web-based interface that will allow you to drive a stepper motor in three different modes using either voltage or current control. It supports an external switch that can stop or reverse the motor, as well as several connections to both the ESP8266 and powerSTEP01 controller.nnYou can also make use of Bash or Python scripts to control the motor without the web-based interface, making it possible to incorporate the WiFi Stepper into your programs or automation sequences. I’ll show you an example using a Bash script on a Raspberry Pi.nnHere is the Table of Contents for today's video:nnnWiFi Stepper Motor Controller - 3:02nGetting Started - 7:13nWeb-Based User Interface - 11:07nSpeed Control Mode - 13:58nVoltage vs Current Control - 18:04nServo Control Mode - 20:44nExternal Step Clock Mode - 22:44nBash Scripts - 27:29nnAs always I have an article that goes along with the video, you can find it at - dbot.ws/wifistep.nnIf you are interested in getting a WiFi Stepper of your own check out the crowdfunding campaign at www.crowdsupply.com/good-robotics/wi-fi-steppernnI’d like to thank Andrew Klofas at Good Robotics for sending me this evaluation board of his product, the WiFi Stepper. I’m looking forward to putting it to use in one of my projects very soon.nnSpeaking of my projects, a lot of new things are happening here in the workshop this spring.
