Arduino Mini CNC Plotter Machine From Dvd Drives By "T4TECHZ" INTRODUCTION : Arduino Mini CNC Plotter Machine From Dvd Driver Follow the video here https://youtu.be/PtbnPl4-yyo I decided to make this detailed guide to help you make it on a few easy steps. Small description: For the X and Y axes we will use two stepper motors and rails from dvd/cd drives and for the Z axis we will use a small servo motor that moves the pen up and down. The Arduino-based circuit is using the ATmega328 microcontroller, two L293 motor driver ICs and an usb to serial module. You can easily make it with the Arduino uno board and an breadboard. You can also use an Bluetooth module (e.g. HC-06) to print your texts (or images) wirelessly through your computer Bluetooth connection! Pretty cool huh? _________________________________________________________ Follow us on Facebook page https://www.facebook.com/T4techz-112021123635521 / Follow us on Instagram https://www.instagram.com/t4techz.
