Contraptor

Great Albanetc!!! I thougth this forum was a bit dead…In fact I have been meshing around Arduino's forum. They have been really kind and comprenhensive there :)
I will try what you suggest, but the point is that there will be no computer to send those commands, I will generate them from the very Arduino! That's why I'm looking for a really lite version of the Gcode interpreter…

Thanks for your reply!

If you want to control the bot from Arduino, you'd have to modify the interpreter code as there is no ready solution (that I'm aware of) that will do that.

As far as I remember, the main loop of the interpreter reads symbols from the serial interface, assembles them into commands and calls the processing routine for each command. You could comment out the serial read code and call processing routine with whatever commands you want the bot to execute.

Thanks again Albanetc! I will try that this very night. I thing I will take out all that is not G1 or similar and try.
