Making a 3 axle CNC machine

I now got grbl into the library folder of Arduino. Still things are worrying. Can You hrlp me?
Trying to load it into tyhe Arduino gives the following error message:

In file included from C:\Users\User\Documents\Arduino\libraries\grbl/config.h:30:0,

from C:\Users\User\Documents\Arduino\sketch_mar13b\sketch_mar13b.ino:1:

#error "Override refresh must be greater than zero."

exit status 1
Error compiling for board Arduino/Genuino Uno.

Moving the statement #include <grbl.h> to the top took the errors away.

What status do my Arduino have now? What is my Arduino capable to now? What can it be used to? How?

I include the message sent:
