Grbl is a popular firmware for the Arduino Uno, Nano, or any other controller using the Atmega 328p chip, designed to turn it into a fully capable CNC controller. So first thing first, What is GRBL? GRBL is a firmware for arduino boards (uno,nano,Duemillanove) that controls stepper motors and spindles/lasers. Using the Adafruit Motor Shield v2 and an Arduino UNO I'm showing how to control 4 stepper motors at once with GCode, the standard language for CNC machines For example, to test the X-axis, send Grbl something like G0 X50 with enough travel distance so that the axis accelerates to its max speed. The GRBL Dual axis homing will automatically abort homing if one limit switch triggers and travels more than 5% (default) of the non-dual axis max travel setting. With a 4th option to use pin D12-13 to control it. A free and full featured gcode platform used for interfacing with advanced CNC controllers like GRBL , FluidNC, TinyG, g2core and Smoothieware.

The CNC Shield V3, paired with GRBL firmware, provides an affordable, efficient solution for controlling three-axis CNC systems using an Arduino Uno. 8 US $58. Using the Mega 2560 board, I have set up the A axis in GRBL under $133 and $134 and calculated the proper number of steps for my regular stepper direct driving my 4th axis - 200 steps, 32 microsteps divided by 360 degrees results in a ‘number’ for A of 17. The components are as follows: Uno R3 Board. An imaginative programmer has adapted GRBL to run 3 linear axes (XYZ) and 3 Rotary axes (ABC) from an Arduino Mega 2560 controller board. I know GRBL supports only 3 axes by default. I finally located and experimented with GRBL Mega 5X on Github. 9 on Arduino Uno is compatible with gShield v5, V. Version 3. 3. Very high performance and flexibility. For example, if the X-axis has dual motors and one X-axis triggers during homing, Grbl will abort 5% of the Y-axis max travel and the other X-axis limit fails to trigger. Yes I know original version of GRBL will not support and there are many issues with UNO board. I'm starting to make bigger is better tabletop cnc machine ASAP and it would be really handy to have 4th axis. An open source, embedded, high performance g-code-parser and CNC milling controller written in optimized C that will run on an Arduino Mega2560 - dguerizec/grbl-Mega-4axis What is GRBL?
