Overview

This is an Opentrons fork of the open-source Smoothieware

Recent Stable Build Here

Smoothie is a free, opensource, high performance G-code interpreter and CNC controller written in Object-Oriented C++ for the LPC17xx micro-controller ( ARM Cortex M3 architecture ). It will run on a mBed, a LPCXpresso, a SmoothieBoard, R2C2 or any other LPC17xx-based board. The motion control part is a port of the awesome grbl.

Materials

Opentrons utilizes the LPC1768 chip

Quick Start

These are the quick steps to get OT Smoothie dependencies installed on your computer:

• Pull down a clone of the Opentrons Smoothie github fork project to your local machine.
• Install GNU-ARM compiler for your Operating System.
• Ensure that your path is correctly set by searching for the location of: arm-none-eabi-gcc/../../bin
• You can check that your path is correct by typing arm-none-eabi-gcc --help and see that the function menu pops up, and also that it is a gcc compiler not a clang compiler

Building and Compiling OT Smoothie

From a shell, switch into the root Smoothie project directory and run:

make clean build

This will generate a hex file which can be added onto an SD card to be placed in a smoothie board that will run our software. If you are receiving an error that the compiler is not being recognized then try the following on a Unix/Linux distro: PATH=$PATH:/path/to/bin/file/gcc-arm-none-eabi-8-2018-q4-major/bin make clean build

If you are connected to a smoothie board, you can use the command

make opentrons

To automatically set up the board for you.
