I think I am working on the same setup as you are right now. Run the Ardunio CNC shield
and Gpredict on windows 10. If so this is what I did.
I am using this site for instructions.
And this link for the sketch and Libraries folder that are needed.
I moved and renamed the folder labeled Libraries over to the Arduino libraries folder and it compiled fine. I think their was one library you have to download thru Arduino IDE and it was something like stepperacel?
You also have to make a small .bat file. For some reason I had a problem getting it to run properly
and the status window to pop up. I could not just click on the .bat file to get it to run. I had to use
the cmd prompt in windows and navigate to the folder with the .bat file to get it to run.
