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
    • NOTE: replace ~/Downloads with the full path where you downloaded GRBL.
  • 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

What the GRBL settings mean, and how to change them

GCode Command Reference

These are the standard GCode commands implemented by GRBL:

My GRBL defaults

$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)
