Welcome to the grbl-LPC wiki!

Building instructions are fairly straight forward. Please keep in mind that these instructions are centered around Windows. Your OS might be different, but the general principals can apply.

First, follow the instructions over at SmoothieWare.org the outline how to start building your own copy of the default firmware. After you can successfully build the default firmware you are mostly ready to build grbl-LPC. Leave your command prompt (Windows) open, as it has all the environment parameters set and ready to build smoothieware.

Second, clone this repository into its own directory. Then follow the instructions found in the readme.txt.

Third, download (see Issue # 1 here) the latest copy of the tool chain. During the install make note of the installation directory and ensure that you don't update your system path with this update. After the installation is over, navigate to to the directory where you installed this update and copy the directories arm-none-eabi, bin, lib, and share into the /gcc-arm-none-eabi directory where your cloned copy of the SmoothieWare environment was placed.

Finally navigate to the cloned grbl-LPC directory from step two within the command prompt open from step one. Enter MAKE and if all goes well, your firmware.bin file is sitting in the /build directory.
