Les binaires de grbl sont disponibles sur le github de grbl. Le version actuellement installée est la version de dev compilée au 25/01/2013

Exemple de commande pour flasher/installer grbl sur l'arduino :

avrdude -C/usr/share/arduino/hardware/tools/avrdude.conf -pm328p -carduino -P/dev/ttyACM0 -D -Uflash:w:grbl_v0_9a_edge_328p_16mhz_9600_build20130319.hex

La version actuellement utilité est une compilation maison de la branche dev au 25/01/2013. Un profil DEFAULTS_CARRNUM, contenant les paramètres par defaut, a été ajouté dans le fichier default.h . Le fichier config.h a été modifié pour que ce profil DEFAULTS_CARRNUM soit utilisé lors du frashage de l'eeprom.
