To compile GRBL and upload to the Arduino
- Download GRBL: https://github.com/grbl/grbl/archive/master.zip
- unzip grbl-master
- Open Terminal.
- Set the following environment variabels (i.e. run these commands in the terminal):
export AVRPATH=/Applications/Arduino.app/Contents/Resources/Java/hardware/tools/avr
export DEVPATH=/dev/tty.usbmodem1411
- (note: DEVPATH should match the name of your currently connected arduino. you can find this from arduino software under Port selection)
export GRBLHEX=grbl.hex
- Add the avr compiler's to your PATH. type this into the terminal:
export PATH="$PATH:$AVRPATH/bin"
- Change to the grbl directory:
cd ~/Downloads/grbl-master
- change
~/Downloads
to match the path where you downloaded.
- change
- Compile GRBL. In the grbl-master director, type:
make
. GRBL should compile. - Upload GRBL to the arduino. From the grbl-master directory, run:
$AVRPATH/bin/avrdude -C$AVRPATH/etc/avrdude.conf -pm328p -carduino -P$DEVPATH -D -Uflash:w:$GRBLHEX

GCode Command Reference
These are the standard GCode commands implemented by GRBL:
My GRBL defaults
$0=28.175 (x, step/mm) $1=28.175 (y, step/mm) $2=250.000 (z, step/mm) $3=10 (step pulse, usec) $4=17780.000 (default feed, mm/min) $5=17780.000 (default seek, mm/min) $6=56 (step port invert mask, int:00111000) $7=25 (step idle delay, msec) $8=500.000 (acceleration, mm/sec^2) $9=0.050 (junction deviation, mm) $10=0.100 (arc, mm/segment) $11=25 (n-arc correction, int) $12=3 (n-decimals, int) $13=0 (report inches, bool) $14=1 (auto start, bool) $15=0 (invert step enable, bool) $16=0 (hard limits, bool) $17=0 (homing cycle, bool) $18=0 (homing dir invert mask, int:00000000) $19=25.000 (homing feed, mm/min) $20=250.000 (homing seek, mm/min) $21=100 (homing debounce, msec) $22=1.000 (homing pull-off, mm)
