right then, As I really like repetier I thought - I'd see about setting up that instead of marlin.

First thing - repetier has a really cool online configuration setup.
You basically work through a few pages of settings and then download either the full firmware with new config or just the config file.
NICE !

It also specifically asks if you have 2 z axis motors and then asks which stepper you want to use for the second motor. Also NICE !

The only issue I have is that I was going to use my third (bog basic) screen. But it's DZ2004A-V1.2 and I have no idea which one I should pick from the list. Obviously nothing has that name - that would be far too easy !

So , for the moment I've stuck the reprap full graphics smart controller in - you never know it might work on repetier.
Failing that - I'll see if I can find a way to use the mks tft touch screen or the real basic screen.

Apart from that it was the easiest config I've ever setup.
Now to move the machine back over here and plug it in and see how the actual firmware upload goes !
