Hello. I wanted to make a three-axis CNC . I bought : - Arduino UNO - CNC Shield - A4988 http://www.banggood.com/CNC-Shield-V3-3D-Printer-Expansion-BoardA4988-DriverUNO-R3-p-967060.html The installation 'm almost ready. My question is when I have to program the ARDUINO . Where I can see some example or as I program . Thank You.
I presume you could use the GRBL software - but I have no experience of it myself.
You can also write your own software. But it would be a challenge if you are a beginner. You may find something useful in stepper motor basics
Definitely play with the Arduino library version of GRBL, since its almost trivial to use:
