I would just like to note that up until this morning we had some pretty bad issues with the E3D hotends, we pretty much had to run them 20 degrees hotter for all materials to get them to extrude properly, this was not the hotend it was our extruder springs! make sure you use the correct springs as this makes a significant difference.
For people in NZ these ones are great (thanks Makershop)

As a good measure the spring coil wire thickness is about 0.81 mm, in terms testing them yourself they are quite painful to fully compress with your fingers.
White-boarded this with one of my co-workers today, hope this covers the system design.
I have created a calibration print for use in calibrating settings in the marlin firmware, this files is available on my github, its pretty basic but easy to use, there is 15cm between the cuts as shown in the image below, measure this with calipers if its incorrect you can adjust and reprint.
So small setback somehow I lost the configuration for dual extrusion in trying to calibrate the printer, I had just installed github on my comp but hadn't uploaded anything yet, serves me right I guess for not having it from the start, will upload the current settings I have but they are not working at the current moment.
Hopefully this can be fixed today!
Today I made sure we could print in 2 new materials we just got also to check quality and confirm heat settings, one is NinjaFlex and the other is HIPS, once we are happy with the qualities we will likely print something in each to CT and test the density of the objects
HIPS - Kindly provided by Diamond Age
NinjaFlex this was purchased from E3D

Printing with PVA and PLA, still got some kinks to work out with the new E3D Heads, as you can see we are seeing considerable oozing when it comes to PVA and a little with PLA, created a nice little test object to print with too.

PVA seems to print well at 220 but maybe thats a little hot considering the oozing...
I got dual extrusion working yesterday Yus!
Garage built, parts sourced from everywhere as long as they were on a budget!
You start with some MDF you grabbed from the free wood pile from outside your local kitchen joinery factory.
Get the fasteners you think you will need from your local hardware store, hopefully with your brother and laws discounts.
Grab some server old rails from a very old server in the "room where computers go to die" at work.
Have you boss give you his oldschool Agfa flatbed scanner.
Buy another flatbed scanner, and some printers on trademe (Ebay).
Order you electronics from Sainsmart with money you gained selling your Honda NS250R motorcycle! :-(
