This repository contains various resources for the development of add-on heads for the FABtotum. For general pointers on custom heads development, see: http://www.fabtotum.com/head-development-guidelines.
WARNING: Firmware support for custom add-ons is not yet stable, therefore actual implementation may change with respect to these information without notice. If you get stuck on something not working do post an issue to let us know, or file a pull-request if you have a possible fix.
You can self-print and make use of this barebone support for the HDB to hack on your custom heads: http://www.thingiverse.com/thing:1832391
Source CAD models are available inside HDB Support, in Autodesk Inventor (.ipt) and STEP (.stp) formats.
The Sketches folder contains Arduino sketches that can be run on a Arduino Nano or similar development board mounted on the FABtotum Personal Fabricator through a HDB.
All sketches are tested to work with FAB-UI/Colibri and a recent version of FABlin (version 1.1.0 or later). You can compile it yourself from the sources or pick one of the released hex images.
