Ahh, I see what you mean about the calibration etc. That all makes sense now thanks.

Well I've sort of got somewhere but also not at the same time.
The guy from RP3D.com (which the old melzi was labelled as) has sent me a firmware file, which you can see in my dropbox account HERE if it's of interest.

He stated that I have to use Arduino 0023 to use this, so I downloaded that version but cannot see in the menu "Tools> Boards" a suitable board option. :(
The Melzi usually has settings of Atmega 1284p and 16mhz, but I have seen comments somewhere suggesting that the Sanguino options can be used since it's based on those. Neither are available in this version of Arduino IDE though?
Is it possible to load more into that list or something?

I tried to use the nearest option of Atmega 1280, but compiling I get a bunch of errors anyway:
