Hi,
I'd like to upgrade my Mendel with an additional extruder. I guess this is something that should plugin to the misc header.

I would like to start working on that, but before wasting my time in duplicate work I have the following questions:

Is there already some work that exists that use the misc header? Could you put me on the right posts/files? What are your plans regarding the integration of multiple extruders?

As far as I could figure out, the toolchain (RepG + Skeinforge) supports e.g. changing tools via support.gcode commands. I would therefore hook in the second extruder as a selectable tool.

As a second extension in mind I would like to have the ability to upload complete gcode programs to onboard memory. The idea is that one can turnoff the PC while printing complex parts. I could imagine having an SD Card or an on board extended memory that would also somehow connect to the misc header...

As far as I could figure out, it seems that the misc header interface somehow implements a serial bus. Therefore I guess it would be possible to have multiple components on that bus, right?

Thank you for your comments,

Cheers
