The '''Athena II 3D printer''' is a [[RepRap]] derived from the [[Athena Build Overview|Athena Delta Printer]], requiring CNC router-cut wooden parts. It is designed to be even easier to assemble, having around 50 fewer fasteners, requiring less wood, fewer printed parts and fewer cables.

Franklin firmware, while developed for all 3D printers, is a perfect fit for the Athena. It natively supports delta printers with built-in positioning algorithms that calculate delta movements (instead of tricking Cartesian firmwares into doing delta movements as has typically been done). It presents the control interface as a web page, meaning that '''no software installation is required on the client'''. It also includes all of the features necessary to take full advantage of Athena's flexibility. For more information, visit [https://github.com/mtu-most/franklin/tree/master Franklin firmware github repository].

Novice builders should be aware that while this design is simple to assemble as compared to historical [[RepRaps]], it is still not trivial. Review the [[MOST RepRap Primer]] and familiarize yourself with terminology and methods. Assembly instructions are detailed and include many images. This is a living document so if a step is missing or difficult to understand, please make an attempt to correct it.

== Printer capabilities/statistics ==

* Print media: PLA; ABS with PLA raft; addition of a heated bed will expand media options
* Filament diameter: 1.75mm
* Nozzle diameter: 0.4mm (can be changed)
* Print volume: 220mm diameter, 210mm high semi-cylindrical shape
* A variety of print controllers can be used; this version uses a Melzi combined with a Beaglebone Green running Franklin firmware
* Energy use: During printing it uses about 40W and slightly more on warm up. e.g. 4 hour print uses 0.23 kWh

== Files and Bill of Materials ==

Available at [https://github.com/phidiasllc/athenaII Github]. Files include OpenSCAD designs and STLs of all components along with the BOM.

== Before You Begin ==

Review the process below and collect all of the tools and consumables you need to begin the build. The list of tools above is not necessarily exhaustive.

== Required Software ==

# Firmware of your choice. '''Franklin firmware [https://github.com/mtu-most/franklin] should be preinstalled for workshops.'''
# A slicer for converting solid models to g-code for printing: [http://software.ultimaker.com/ Cura slicer] or [http://slic3r.org/ slic3r] or other.
# A printer interface: the choice of interface depends upon the firmware selected. Franklin requires only a non-Microsoft web browser (i.e. not MS Edge or MS Internet Explorer).

== Assembly ==

Assembly is organized by functional group.

For those participating in workshops, some of the assembly is completed before the workshop. Only those parts of the process highlighted green are required.
