It is nearly impossible to read emotion into text, a study was done that showed that people -thought- they were 90% accurate at reading intent into emails, when in fact they are 50%.
So I'll state as clearly as I can: this is said without sarcasm, and with lack of malice.
You have just told everyone in the forum that you are lazy. You want someone to give you the code already written for an Arduino to run a RepRap. But you've not even done enough research to know that RepRaps are almost without exception run by Arduinos, and that the complete code is freely available. And you have not even tried typing "RepRap" into a search engine, or you'd know this already.
You received a critical piece of advice, and completely ignored it, told us you want all the work done for you, and that you'll probably just buy a kit, anyway.
No one here is paid for their time. We help other people because we're paying it forward, expect others to do likewise, and because we expect help in return.
Again, complete lack of sarcasm, no malice.
If you really are serious about this, go here and do a lot of reading:http://reprap.org/wiki/RepRap
Only after you have read through that, then go here and ask your questions about RepRaps:http://forums.reprap.org/
