How to print with both extruders on the same print?

Let’s say that I want to print a planetary gear http://www.thingiverse.com/thing:53451 but want the outer and center gear to be yellow and the other gears to be blue. How do I do that?

Cheers,
John

to print dual color object ,first you need have a model separate into two parts and have the same origin .
here is a video about how to print with dual head you can have a check https://drive.google.com/file/d/0BxAApICl23VCRFdhd01Mdm1Jajg/view?usp=sharing

Thank you, it will be very helpful once I get the second nozzle fixed. It got hung up on a raft and broke. I ordered another but didn’t specify that I needed the PEEK as well (actually that’s all I needed) so the repair failed. I will order 2 nozzles with PEEK this time as well as new PEEK if I can. So for now, it’s a single nozzle printer. :smile:

Cheers,

I recently purchased a Grid II Dual. I am very interested in learning how to use both extruders on the same single object being printed. The video bo_zou posted was done with Chinese version of the ReplicatorG. It would be really helpful if the English version was posted as well.
