That means the contr *Important note for Atmega 168 users:* Grbl used to be compatible with both the older Ardunios running atmega 168 and the newer with 328p. This had to go, as I was unable to fit the acceleration management into the 16k code space of the 168. If you want to run Grbl on an 168 I am still maintaining Grbl 0.51 "in the branch called 'v0_51'":https://github.com/simen/grbl/tree/v0_51. +*Note for users upgrading from 0.51 to 0.6:* The new version has new and improved default pin-out.

This is a simple matter of editing config.h – the whole legacy pin assignment is there for you to uncomment. + _The project was initially inspired by the Arduino GCode Interpreter by Mike Ellery_
