Help me please ((

Hi guys
This my first reprap Mendel
After i finish all mechanical part
I install slave controller
And connect all wires in its place

I start with software
I setup sli3er and pronterface
Then i setup the five python file to my windows 7
Then i open the sli3er and choose the usb port after that i click on " connect "
,few second it show me " reprappro slave controller restarted "
Then i click on "Get Pos" that appear a message in command window " printer is not online "


BTY : someone told me to go for reprappro.com in troubleshooting section #6
I tried that way but did not work ( when i press on reset on slave controller the same message i get " reprappro slave controller restarted "




This is all what i did in software
If there any required software i miss or any step i forget
Please tell me how to fix it
I suppose to summit the all " reprap mendel 3d printer tomorrow

Wath firmware do you use ?
Is this the same in firmware and in pronterface ????

From marlin !!!!!!!!!!!!!!!!!!!!
