This project is a customized fork of GRBL, tailored to support multiple machine types and board configurations. The firmware includes build targets for each machine, allowing seamless configuration and flashing.

1. Arduino CLI: Ensure Arduino CLI is installed. On macOS, you can install it with Homebrew:

brew install arduino-cli

Arduino AVR Core: Install the AVR core for Arduino boards:

arduino-cli core install arduino:avr

Make Utility: The make utility is typically pre-installed on macOS. If not, install it:

brew install make

This GRBL fork supports different configurations for machine-specific firmware. The build process uses make commands to compile firmware for the desired machine. Build Targets

RC Mini Firmware:

make build_rcmini

The compiled firmware will be output as build/rcmini.hex.

Bamboo Firmware:

make build_bamboo

The compiled firmware will be output as build/bamboo.hex.

Both Machines:

make

This builds firmware for both RC Mini and Bamboo, placing the output files in the build directory.

After building, you can flash the firmware to your connected Arduino.

Flash RC Mini firmware:

make flash_rcmini

Flash Bamboo firmware:

make flash_bamboo

These commands will:

• Detect a connected Arduino on a /dev/cu.usbmodem* port.
• Compile the project if necessary.
• Flash the respective firmware to the Arduino.

To remove compiled files and clean the build directory:

make clean

No Arduino Detected: Ensure your Arduino is connected and recognized by your computer. Run the following command to verify its presence:

ls /dev/cu.usbmodem*
