Communication Problems

I am trying to finish up my printer, but I have ran into a problem with the Repetier host software. I can connect to the arduino in the arduino interface. I can upload the firmware and even connect in the reptier host program. The problem is that the printer dose not respond to any commands that I send it. I have no idea if it is a software or hardware probelm. Any help would be much appreciated.

Power supply working and connected correctly? What electonics are you using?

Yes. Im using the ramps 1.4 with arduino.

Do you have the baudrates matched? If they aren't, Repetier Host will say connected but will have "Commands Waiting".

Some computers have problems with 250,000 baud. Try 115,200 baud on both ends and see if that works.....
