OK after much trial and messing around i've managed to somehow get it to upload. Only problem now is that the LCD display is still displaying the two bars and none of the firmware i've just uploaded.

I think this actually an error in the code somewhere, I've just tried to boot on another PC and i get the same error code but a different com port.

Yeah i've allocated it to COM6 in both device manager and in the arduino ide. I've just restarted my pc and it's still throwing the same error. Totally no idea at all to this problem.

Your device is not being found on COM6. Are you sure it is actually on COM6?

Same issue when I try with Marlin.

Sketch uses 50,828 bytes (20%) of program storage space. Maximum is 253,952 bytes.
Global variables use 2,849 bytes (34%) of dynamic memory, leaving 5,343 bytes for local variables. Maximum is 8,192 bytes.

Yes but I have a different LCD, i've found the firmware but now I'm having issues uploading it to the arduino.

Arduino: 1.6.7 (Windows 10), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

Sketch uses 67,162 bytes (26%) of program storage space. Maximum is 253,952 bytes.
Global variables use 2,921 bytes (35%) of dynamic memory, leaving 5,271 bytes for local variables. Maximum is 8,192 bytes.
avrdude: ser_open(): can't open device "\\.\COM6": The system cannot find the file specified.

avrdude: ser_drain(): read error: The handle is invalid.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with

enabled in File > Preferences.

I think that you mean you can't get a display to work? Something like this? http://reprap.org/wiki/RepRapDiscount_F … Controller

I recently got a RAMPS kit but when I go to power it all up the screen is just displaying black bars with the backlight. Am i correct in thinking that the repetier host isn't already pre-installed and i need to do so myself ? If so where can I get the correct files from as I cannot get any so far i've found to compile correctly in arduino 1.6.7.
