I have followed fabduino
instruction...

first trial I burned the microcontroller while trying to program it....
It is really hard to connect it with avrismpkii...
.
second trial....success...it had worked for days...
With it I have experimented using arduino IDE and seen differentiated
blinking code outcome.
I have again forgot about documentation- and it stopped working while I
was using it for my final project.

This is the only documantation that I have... The screenshot while
adding grbl code on fabduino....flashed successfully....
