Hi Paul,

I've just built a delta from a cheapo Chinese kit.  Wasn't necessarily good
value :-)

Sounds like an LCD issue - similar to the forum thread I see you already
posted on.

Sounds like the Arduino works - can be reflashed.  When you plug/unplug it,
you should be able to see a serial port appear/disappear (dmesg).

Once the firmware is there, I'd expect it to talk a form of G-code - all 3D
do AFAIK.   http://reprap.org/wiki/G-code

You could use your favourite terminal program to talk some G-code at it.

Alternatively, one of the many printer control programs.  I use Printrun
https://github.com/kliment/Printrun  (which follows the *nix
pseudo-convention of
weird command names - pronterface, pronsole).

Double check the electrical connections to the LCD?  Then ask for a
