I have looked at several instructables, and youtube videos, and have done hours of research and note taking, trying to get mine to work. My build is a bit different, as I am using 3 CD-Rom steppers, one for each axis.
I am using an Arduino Uno, with the CNC shield, grbl controller v3.6.1, and grbl v1.1.
I started with just the Arduino and shield, and found, and modified a sketch that runs all 3 axis back and forth, just to test the mechanics. I made a short video of it running.
I am willing to share the video and the sketch, if you are interested.
Even though Arduino controlled 3d printers are becoming very popular, and cheaper to buy, there does not seem to be a clear, concise place to find information on them.
Each internet resource I've found leaves out critical info.
All my work with Arduino CNC is in support of building a table top router/engraver for small projects. The CD-Rom stepper machine is a training aid!
