Hi Vitaly,

I did exactly as you described it. I made a folder named "reprap_new_firmware" with all the files from "reprap_new_firmware.zip". After that I opened that folder and got all the files opened in tabs. When I try to compile it i get this error messages:

Fehler: »char word [128]« als andere Symbolart redeklariert /usr/local/arduino-0017/hardware/cores/arduino/wiring.h:97: Fehler: vorherige Deklaration von »typedef unsigned int word«

In function »void loop()«:
In function »void init_process_string()«:

translated:

Error: 'char word [128] "as the other symbol type redeclared /usr/local/arduino-0017/hardware/cores/arduino/wiring.h: 97: error: previous declaration of' typedef unsigned int word"

The compiler points to

#define COMMAND_SIZE 128
char word[COMMAND_SIZE];

in tab "reprap_new_firmware"

Are there some extra adjustments to do?

Regarding "grbl", which you mentioned in Arduino GCode Interpreter as an alternativ. Do I have to compile it with "make" and upload emerging "grbl.hex" via avrdude to the arduino?

Looks like "word" is a defined type in Arduino 0017. Looking at the code, this variable used in interpreter to accumulate characters from serial input and pass them on for execution once new line is encountered. Just rename "word" into something else, e.g. "command", there are 4 occurrences total.

The reason I didn't get this error is because I've been using Arduino 0012 - it's the latest version with which the compiled interpreter fits into Diecimila (and only on Ubuntu, I think). I have since ordered a couple of Duemilanove boards with more memory, but alas have not had time to try them.

As far as grbl, I haven't really looked at it at all, just seen it mentioned as an alternative GCode interpreter which can run on Arduino.
