About Grbl
Grbl is a free, open source, high performance software for controlling the motion of machines that move, that make things, or that make things move, and will run on a straight Arduino. If the maker movement was an industry, Grbl would be the industry standard.

New features in v0.9!
Default serial baudrate is now 115200! (Up from 9600)
Z-Axis limit input on D11 has swapped with spindle enable D12 to support variable spindle PWM output.
No QUEUE state: Queue was removed due to it being redundant. Holds now suspend Grbl and only allow realtime commands. Cycle start resumes, and reset exits.
NEW Super Smooth Stepper Algorithm: Complete overhaul of the handling of the stepper driver to simplify and reduce task time per ISR tick.
Stability and Robustness Updates.
(x4)+ Faster Planne.r
Variable Spindle Speed Output.
Compile-able via Arduino IDE!
G-Code Parser Overhaul: Completely re-written from the ground-up for 100%-compliance* to the G-code standard.
Independent Acceleration and Velocity Settings.
Soft Limits: Checks if any motion command exceeds workspace limits before executing it, and alarms out, if detected.
Probing: The G38.2, G38.3, G38.4, & G38.5 straight probe G-code commands are now supported and connected through the A5 pin.
Tool Length Offsets.
Improved Arc Performance.
New Grbl SIMULATOR! : A completely independent wrapper of the Grbl main source code that may be compiled as an executable on a computer. No Arduino required. Simply simulates the responses of Grbl as if it was on an Arduino.
CPU Pin Mapping.
Configurable Real-time Status Reporting.
Updated Homing Routine: Sets workspace volume in all negative space regardless of limit switch position.
