Introduction

This support page contains a quick introduction to using the great g2core CNC controller software in combination with Djuke products like the Djuke g2core shield and the Djuke Alu30 CNC machine.

The g2core github project was forked to add some minor fixes and example configurations for my machine:

Linux

Required tools

sudo apt-get install git-core make bossa-cli

GIT checkout

It is up to the user to choose between the more stable 'master' branch or the development 'edge' branch with the latest features. Make a local GIT clone of the repository using either

git clone https://github.com/synthetos/g2.git -b master --recursive

or

git clone https://github.com/synthetos/g2.git -b edge --recursive

or

git clone https://github.com/Djuke-DIYAudio/g2.git -b edge --recursive

Adjustments

Because the Arduino Due does not have an EEPROM to store persistent settings it is advised to make your own settings file containing your machines configuration and build a custom g2core firmware which includes this configuration. Copy from e.g. settings/settings_Djuke_test.h and adjust it for your situation.

Hints:

• If you want to use the Due spindle direction pin 13 for automatically setting the spindle direction, adjust the following line in gShield-pinout.h (Note that this fix is already present on https://github.com/Djuke-DIYAudio/g2)

  pin_number kSpindle_DirPinNumber            =  13;

• If you want to use a GRBL CNC shield on the Due with a common motor enable pin 8, use the 'master' branch as the current (100.21) 'edge' branch does not set this pin properly.

Building

cd g2/g2core (for edge)
cd g2/TinyG2 (for master)
make BOARD=gShield SETTINGS_FILE=settings_Djuke_test.h
