Problem Updating to Grbl 0.9

I have downloaded the file and processed the library using the “Include Library” “Add .ZIP Library” then tried to execute the build process in Audrino 1.63 and Audrino 1.64.

When I load the “grblUpload.ino” try the upload process it aborts and gives me the following:

Arduino: 1.6.3 (Windows 7), Board: “Arduino Uno”

grblUpload.ino:27:18: fatal error: grbl.h: No such file or directory

compilation terminated.

Error compiling.

This appears to be the Aurdino IDE not properly finding the library after importing it since the file “grbl.h” is clearly in the directory.

Any thoughts or ideas?


@ScottWillis What is the name of the grbl folder in your libraries folder? It should be…

  • Arduino
  • libraries
    • grbl

…not grbl-master

Did the trick, My bad must have missed something in the instructions.


@ScottWillis …easy one. I have made the same mistake. :smile:
