SOLVED RAMPS 1.4 not found in pronterface windows7 Help!

I build a RAMPS 1.4 with lcd on a arduino 2580, programmed it with Merlin but can not connect with pronterface or any other program.
In win7 settings I see a new serial port com 4 from the arduino.
In pronterface (or any other) i choose com 4 and speed 115200 (tryed all the others too), but the program doesn't find the board.
With Arduino 1.01 it programs fine (prove the working LCD show temp 26 and printer ready)
Can somebody help me?

Thanks in advance.

Changed the baudrate in configuration.h to 115200, problem solved

hi wrangler

I am having the same issue you had previously. You mentioned that you solved the problem by modifying configuration.h, where can I find this file? I searched under the Printrun&pronterface folder, I could not find this file.

Please let me know

thanks

Configuration.h is part of the firmware. If you are using pre-loaded firmware and don't want to upload a new one, then you will have to set the baud in pronterface to match the default of the firmware. For Marlin, the default is 250000.
