I’ve finished rewriting the zapmaker fork of the GrblHoming project on github – lots of code refactoring to fix bugs and harden the code.
Couple of major cool new features: Native Mac support and ability to reset the Arduino from the user interface – don’t need to hit the reset button on the ‘duino any more.
Check out Grbl Controller on github. Download installers for Mac, Windows and Linux.
Grlb Controller featured on the Shapeoko wiki.
Let me know how it goes!
