The OpenBuilds ACRO System was developed to be the most accurate and cost effective positioning system in its class. The ACRO System incorporates the OpenBuilds V-Slot system and, therefore, has the unique ability to expand to multiple sizes creating a size configuration custom to your needs. Choose the size that best fits your workshop. This versatile system allows for precise positioning of many different mountable tools and attachments.

Another slight variation of Niko's Eggbot using Openbuilds V-slot and other 3d printed parts.

My version of the Mug Plotter designed by Teed http://edinburghhacklab.com/ . Also used the Eibotboard from the original eggbot from evilmadscientists http://shop.evilmadscientist.com/partsmenu/188-ebb A huge thanks to Hexitex for his brilliant Four jaw chuck http://www.thingiverse.com/thing:5791

This EggBot design has a perfect functionality (the same as the original EggBot professional), a perfect cable and microcontroller arrangement, and a perfect cost as it uses a minimum list of parts (with one V-Slot Linear Rail size20mm x 80mm and length 500mm you can build 3 EggBots!)

I creat a open source 3D Printer to print big things. Print size: 400x500x300 mm. You can download the Drawing in PDF and in Inventor 2013 format. The unwinding drawings are also included. I take some detail photos for a better understanding.
