µCNC for AVR can be built in a couple of ways

Method one - Using the makefile (preferred)

  1. Download and install GCC tools for AVR inside your PC. You can download the latest version of GCC tool for AVR from Microchip from here.
    • If your are compiling with this method on a Windows machine you will also need to install Make. You can download Make for Windows from here.
  2. Go to the uCNC src folder and edit the board cnc_config.h file if you need to select a different AVR board. µCNC is configured by default to mimic Grbl pin configuration in the Arduino UNO board.
  3. Go to the makefiles/avr folder.
    • The makefile is configured by default to compile the code for the MCU (atmega328p) and working frequency (16Mhz) in Arduino UNO board. If the chosen board has a different MCU/working frequency the makefile must be adjusted by modifying MCU = atmega328p and F_CPU = 16000000UL
  4. Open a command console inside makefiles/avr folder and run make
  5. If everything went well you should have a hex file inside makefiles/avr/build folder
  6. Now just upload µCNC to your board using an appropriate tool. xLoader for AVR is an easy tool to use.

Method one - Arduino IDE
