Dual Extruder Dual X-Carriage Bukobot 3D Printer

BuidRob made a custom Bukobot with independently movable dual print heads. It looks AMAZING!!!
This could become a standard feature in the near future ...

Advantages of separate x-carriages:

• The inactive extruder can be parked when not in use.
• The inactive extruder can be easily capped when parked to prevent runout / ooze (which makes restarting the print more accurate).
• Each x-carriage is almost half the weight which allows higher print speeds with less backlash.
• The x-carriages can duplicate one another allow two copies of an object to be printed at one.

Demonstration of duplication mode:
