Why don't you use Makerware, it's easier.

Hi I need help on dualtrusion, how are we going to merge when there are 4 files like his ? I am using repg for gcode ,

I think one of the problems is that Creo Elements Express doesn't show me where the origin of the model is. Therefore I have to reposition it in ReplicatorG. In order to see if the two colors are positioned correctly, with respect to each other, I use gcode2vtk from bkubicek, which is really great. Unfortunately when I load the vtk-file into ParaView the origin is way outside the model. Hence I don't know if the model is correctly positioned for printing.

Placing cubes might be a solution. But Ifirst have to check if disjoint bodies can be merged to one in Creo.

Instructions

Print the model in white and orange.

I don't know if the gcode is any good since there's no control over dual extrusion models in ReplicatorG.

@ Makerbot, please add some sort of control to ReplicatorG such that the user is able to see both models at the same time. Otherwise it's pretty much impossible to check the relative position of them.

Update:
I uploaded an improved design (files: "..._Rings_Orange.stl" and "..._Rings_White.stl") in which the parts of each color are disjoint. I used OpenSTL from Wei Li to merge the disjoint parts for each color together since this cannot be made with Creo Elements Express.

If you generate the two STLs from the same source, and don't reposition it in ReplicatorG, it should be fine.

Alternatively, you can place cubes in the corners, such that 'center' then 'place on platform' aligns the geometry.

You can verify the generated GCode by opening it in Pleasant3D (on the Mac) where you can look at the generated GCode paths. I don't know what the comparable PC tool would be.
