can't find GRBL in Libraries

Development Tools IDE 1.x
1

I'm new to Arduino, bought a Uno (Rev3) and a motor shield to suit.
Using Dell "Inspiron" with windows 10. Now I find that the GRBL .Zip which I downloaded from GitHub does not contain a "valid library" yet it is listed in Documents/Arduino/Libraries. Can't find it in "Managed Libraries" either.
There is nothing connected to Uno apart from USB to Dell and power from the wall socket. (no motors, spindle or laser).
I have asked Dr Google and tried 2 options. GitHub's help page is beyond me. What else can I try?
:confused:
Thanks!

If you installed it properly then look under EXAMPLES.

It should be listed there.
Initially you should load GRBL to the Arduino without the cnc shield.

As for the HOW TO then Dr Google has more than enough help for it.

Could you take a few moments to Learn How To Use The Forum.
Other general help and troubleshooting advice can be found here.
It will help you get the best out of the forum in the future.

The cause of the problem is that the authors of GRBL didn't structure their GitHub repository in a manner that makes it easy to install. For that, the library would need in the root of the repository, but instead it's in a subfolder.

Do this:

  • Delete your attempted installation of GRBL from Documents/Arduino/libraries. Please be very careful when deleting things from your computer. When in doubt, back up!
  • Download GRBL: https://github.com/gnea/grbl/archive/master.zip
  • Unzip the downloaded file.
  • (In the Arduino IDE) Sketch > Include Library > Add .ZIP Library
  • Select the grbl subfolder of the unzipped folder.
  • Click the "Open" button.
  • File > Examples > grbl > grblUpload
  • Connect your Uno to your computer with a USB cable.
  • Tools > Board > Arduino Uno
  • Tools > Port > select the port of your Uno
  • Sketch > Upload
  • Wait for the upload process to finish successfully.

You now have GRBL running on your Uno.

:grin:
Thanks for your help, gentlemen.
Finally got this done following Pert's advice except I went further into it by uninstalling IDE and deleting anything that said GRBL. Then I went back to GitHub and finally found the .zip file and downloaded and extracted it.
After re-installing IDE I went to "Sketch/Include Library/Add .zip folder" only this time I chased down the .grbl file instead of the .zip folder containing it.
Success at last!!
Thanks again.
