This is my design for a 400mm x 430mm x Infinity belt printer.  The main design works around a CoreXY D-bot design.  I've integrated the use of Linear rails and have designed the  mount for the E3D V6 or Mosquito hotends(but mosquito fits without any modifications to the hotend".  
Currently the only slicer that I am aware that works with belt printers and can handle the 45degree angle is Cura Blackbelt.

I uploaded the files to GitHub for future ease of collaboration and in hopes as a community we can make this printer "Perfect"
