I was reorganising the cabling after I installed the cooling fans next to the hot end. I checked there were no loose ends and everything seemed to be fine. But as soon as I turned the PSU on there was a faint popping sound and no lights on the LCD. I managed to connect wires from PSU to RAMPS wrong way and that instantly fried RAMPS.
Looks like the LCD and MEGA are okay though, I was able to turn them on with USB power and use different features on the controller. However, none of the steppers move and the hot end wont warm up. Just to make sure I decided to order new RAMPS, MEGA and stepper drivers again. This will mean couple weeks pause with printing but I'll use that to design and build an enclosure for the printer.

Marlin firmware
In order to get Arduino Mega clone and RAMPS board to function properly I need to install a firmware to Arduino. There are several choices but I decided to start with Marlin. It seems to be actively maintained and has good support.
I downloaded release version 1.0.2 and started to work with the configuration file. I did not modify too many settings at this point. I only selected correct motherboard settings and enabled LCD support. After uploading the firmware I disconnected Arduino and pressed the RAMPS board on it. I also hooked up the LCD screen cables and powered everything up. The LCD lit up and the menu was operational so I guess it works ok.

Electronics arrived
We had a postal strike here in Finland so not much happened for a while. But today I got some packages! My Arduino Mega clone, RAMPS and bunch of other stuff arrived.
I have an original Arduino UNO so the Arduino IDE was already familiar to me. I'll leave installation of the electronics for the weekend but I wanted to test the Mega board first. But it did not work straight away with OS X 10.9. The simple LED blinking code refused to upload to the board. The error was following:
avrdude: ser_open(): can't open device "COM1": No such file or directory ioctl("TIOCMGET"): Inappropriate ioctl for device
So after a couple searches I learnt I should install a new USB driver. The instructions and driver can be found here: http://kiguino.moos.io/2014/12/31/how-to-use-arduino-nano-mini-pro-with-CH340G-on-mac-osx-yosemite.html
After running the installer and reboot the Arduino IDE was able to upload the code and LED blinker works fine now.
