This is a detailed guide on how to control stepper motors using the Arduino CNC Shield V3 using GRBL and the Universal G-code Sender. This CNC Shield was designed to provide an inexpensive solution for controlling stepper motors for different types of DIY CNC machines including and other projects that need precision control of stepper motors. The Arduino CNC Shield uses the A4988 and DRV8825 stepper motor drivers therefore in case you are not very familiar with the working of these drivers, you can make reference to my other tutorials on how to use these drivers; - https://youtu.be/ODREz3vy2_Q - https://youtu.be/NrKMpnL9iCY To get the code and downloads for GRBL and Universal G-code Sender visit: https://mytectutor.com/controlling-stepper-motors-using-arduino-cnc-shield-v3-and-grbl/
