First contact

The cartesian framework, electronics, firmware and host are now fully connected.

My findings
GCode_interpreter, SVN version #2540
- despite the comments in parameters.h the optostops seem to be inverting so #define ENDSTOPS_INVERTING 1
- for reasons not yet clear the X direction was reversed, hence #define INVERT_X_DIR 1

Java Host, SVN #2539
- testdrive works (move, nudge and HOME positioning of X, Y and Z)
- demo print (the extruder is not yet connected) with m3.stl from RepRap parts results in the same Java Error as two weeks ago (with SVN #2452): Production exception: java.lang.NullPointerException. Printing to .gcode file results in Production exception: java.lang.ArrayIndexOutOfBoundsException: -1

Analyzing this with the NetBeans IDE. Also see RR software forum entry.
