Hi Guys,
short story:
Read a lot about 3D printing, have some degree of experience with electronics, Arduino and physics, and thought I'd take a shot at it.
I compared and compared again, and bought a DIY kit from reprapworld.com. Along with a Megatronics V2.0 all-in-one board.
I spent about 3 days at building the raw frame, following the very good
instructional videos on the wiki.
This worked out allright, until I got to hooking up the electronics.
The board is quite young, so I'm not finding a lot of documentation, this is what I got:

firmware
BUT nowhere I can find information about the polarity of the pins on the board, so I'm afraid to fry board or drivers by hooking them up the wrong way.
The guys from reprapworld were kind to swiftly reply to my questions, but I think it is in the interest of everyone that I ask it this way.
Thanks for the advice!
Dirk
