FABlin Firmware
                    ===============

for FABtotum Personal Fabricator and FABtotum Core platforms

This is FABlin, a Marlin derivative firmware. Marlin was originally created by Erik Zalm (https://github.com/ErikZalm/Marlin). The changes made are focused on multipurpose personal fabrication and hardware characteristics of the FABtotum Personal Fabricator such as 3D/4 Axis milling, 3D/4 axis scanning, Touch-probing and the Totumduino Board I/Os capabilities.

Compiling

with Arduino IDE

To correctly compile the firmware with Arduino you must set the folder where this repository is checked out as Arduino's sketchbook folder inside Arduino's preferences. Alternatively you can manually copy the FABlin/libraries/SmartComm folder into your current sketchbook's libraries folder.

For further info refer to https://www.arduino.cc/en/Guide/Environment#toc7.

with PlatformIO

A default platformio.ini file with correct directories definitions is now included in the repository. To compile the firmware simply run:

platformio run

inside this repository's root folder. To upload the firmware on the board or flash it directly into it refer to platformio documentation. platformio.ini has a default definition for using an AVRISP-mk2 usb programmer. To directly flash the firmware onto TOTUMduino using that defintion, run:

platformio run -t program
