ofxGrbl2
openFrameworks addon for easily sending GCode commands to a device with GRBL firmware
This addon was at first a fork of https://github.com/TsubokuLab/ofxGrbl but then I refactored so heavily that I decided to make it a different addon.
Important
This addon is still a work in progress, so don't expect it to work right now, although you can try it if you want.
