Port of grbl for the Multibot
This is a port of grbl 1.1h configured to run on a cnc shield and my Multibot machine. https://github.com/gnea/grbl
Only one file is currently modified, config.h. I have the origional config_org.h file as well so you can easily see the changes I have made. This assumes you have an official Pronter CNC shield and not a chineese clone. That allows us to use the laser and auto squaring of the y axis at the same time. https://blog.protoneer.co.nz/arduino-cnc-shield/
This is setup to work with the Multibot CNC project. You can find the 3D print files on https://www.thingiverse.com/thing:4645791 and you can read up more on the project at https://hackaday.io/project/176110-multibot-cnc-v2
