cOssel delta 3d printer by Chris Dieringer

cOssel is a Rostock / Kossel derivative by Chris Dieringer. It does a few things differently from other deltas, still the central design and technology is the same. Main features are:

• OpenRail for linear motion 
• Dual hot end configuration 
• Bowden extruder designed for geared steppers 
• Mechanically fixed heated bed, vs. binder clips
• cOssel attempts to enable a low-power, non-contact automatic leveling sensor as an alternative to using a retractable mechanical switch as used in other deltas. This feature is still experimental as most IR sensors have not been proven repeatable.

cOssel has dual reflective IR auto leveling,  This feature is still experimental as most IR sensors have not been proven repeatable.
