Arduino BIG Stepper Motor control. Rotary Axis for milling machine.

Wiring connections – Arduino Pin 8 to stepper driver pulse +5V – Arduino Pin 9 to stepper driver direction +5V – Arduino Ground to stepper driver signal ground Pulse -ve, Dir -ve, enable -ve – Arduino +5 volts to on/off switch to stepper driver enable +5V   Helpful hints: 1. Pick the size of motor you need for the torque/power you need. Don’t know? FIND OUT! 2. Determine the voltage and current of the stepper motor. 3. Determine the stepper motor driver that will power your stepper motor with some extra fudge factor (this stuff is cheap). Big Easy driver…

Homemade DIY CNC – ClearPath Servo Motors used on KR33 CNC

Many have asked what motors I’m using on the KR33 Mini CNC so I wanted to do a video specifically on the topic. The motors are ClearPath Digital Servo motors by Teknic. I communicate with them the same way that I’ve done with stepper motors, with step and direction commands. The speed and power is fantastic. The servo motors power doesn’t fade with speed like steppers do.  

Arduino Stepper: Ultimate Accuracy!

I’ve always loved automation equipment! A grade school trip to a museum with a marble machine using pneumatics, sensors, servos and more had me hooked.   Combining Arduino’s with mechanical devices and machined parts is just amazing. I’m working on a project using a stepper as a “feed device” and wanted to make a video experimenting with various ways to control the Arduino Stepper as well as measuring to see just how accurate it could be!  

Wireless RF Remote & Receiver! Easy & Cheap! Great for Arduino and Raspberry Pi!

A review of Adafruit’s inexpensive RF keyfob remote and receiver. This is by far the easiest and least expensive RF solutions I’ve seen! It’s a “turnkey” solution – e.g. it works right out of the box. It can directly control things (like an LED or transistor) or be used to trigger a digital input pin on an Arduino or Raspberry Pi!  

Arduino Wireless Mobile Data Logger with Sonar and Xbee

Measures and logs temperature and light levels.   Two mode of operation: Automated – moves on its own avoids obstacles using distance sensor. Also plots the distance/sonar data into processing Manual – Manual Control using keyboard or buttons on the application.   Wireless control and data acquisition: Communications using to Xbee modules. Base Xbee used to transmit data form custom processing application. Base Xbee used to received sensor data sent from the mobile data logger.   Processing Application: Display data received from mobile data logger Display sonar data when in automated mode Send control data to mobile data logger using…
