Need help! Prusa I3 Light

[Loperenco]

Hello guys!

I'm happy to register here as I had big issues with my printer, which I cannot solv by my own nor with my friends. I'm really hoping that I will find good soul here that might help me!

So, I've bought 3D Printer called Prusa I3 Light. I will post here a link to the seller, don't know if its legal here, but it's only to show You which printer I'm talking about:
http://store.propox.com/index.php?p3080,prusa-i3-light
There is written that it is Geetech printer, but I couldn't find it in Your offer nor elsewhere in google :/

My problem is, that the seller, did not include working firmware and other soft like repetier, also the problem is that I'm newcomer in 3D printing, all I managed to do was to
configure Marlin and Repetier as far as printer is listening to move orders from repetier, but is not willing to print if I give it order by repetier itself or SD card.

I would love to find a person, who could give me some files with working Marlin for this printer!

I'm counting on you! Every single comment counts! Thanks!
