To flash GRBL to Arduino from Terminal

• Download GRBL: https://github.com/grbl/grbl/archive/master.zip
• unzip grbl-master
• In the Terminal set the following environment variabls:
  • export AVRPATH=/Applications/Arduino.app/Contents/Resources/Java/hardware/tools/avr
  • export DEVPATH=/dev/tty.usbmodem1411
  • export GRBLHEX=grbl.hex
• Change to the grbl directory: cd ~/PATH_TO_DOWNLOAD/grbl-master
• Compile GRBL
  • From grbl directory, run $AVRPATH/bin/avrdude -C$AVRPATH/etc/avrdude.conf -pm328p -carduino -P$DEVPATH -D -Uflash:w:$GRBLHEX
