Sunra, the updated post I will be making won't really focus on the actual hacking process so much as it will focus on the post-hacking process. The link provided earlier in this thread by Dominick (https://github.com/luc-github/Repetier-Firmware-0.92) is quite sufficient to walk any beginner through the process of flashing his DaVinci. There's also a link towards the bottom of that writeup that you can follow to youtube in order to watch the exact process being done on a 1.0. All you need to do differently for the 2.0 is jump the J37 pins on the board, and change a few 0's to 2's or 3's in the line of code generated by the Arduino software before you actually tell it to flash your printer (the GitHub link explains how to do this thoroughly so no worries, it's very easy).
The post I will be writing soon will focus on what to do after you have successfully flashed it. I aim to answer questions like the following:
How do I setup/configure my 2.0 Duo for use with Repetier Host?
How do I print using the Repetier Host?
What to look for in my first print after the Repetier Flash?
These are only a few of the things I will be going over. Their all things I encountered when starting to use Repetier and Slic3r, stuff that will e extremely useful to people who have never used anything other than the XYZware with their printer.
I think you will find it very useful Sunra, especially if you ever plan to flash your Duo
