I've been waiting for this to hit Kickstarter!
I met the qu-bd folk at the San Mateo Maker Faire and had a chance to look over their extruder. It looks like it would be a good fit on the ORD Bot.
My plan is is to use their dual setup to upgrade my ORDish bot.

What heating element is included?
A 6.8Ohm, 3 watt power resistor is included in EVERY kit. We have found these to be very reliable and can provide more than the required amount of heat for extrusion of ABS and PLA plastic. Additionally we have a heater cartridge available for an additional $14. It is a professional grade, 12v / 40 w heater cartridge with insulated leads. It can get to extremely high temperature, stably and safely; it also offers a 'cleaner' looking installation with the sheathed wiring. For those that want to experiment with high-temp materials, the heater cartridge upgrade is worthwhile
Congratulations!
You are now an official backer of Open Source Universal 3D Printer Extruder | DUAL EXTRUSION |.

The controls won't know I'm building two parts at once, a few inches apart.
