I didn't understand the instructions how to install the GCode interpreter
In arduino-gcode-interpreter is written to get an idea to look at http://reprap.org/bin/view/Main/Arduino_GCode_Interpreter but to use Chris Meighan's rewrite.
How meets the rewritten interpreter the installation instructions on http://reprap.org/bin/view/Main/Arduino_GCode_Interpreter
Once you download the proper files, there are a couple steps you need to do:
1. Copy the folders in reprap-arduino-firmware-x.y/library to arduino-00xx/hardware/libraries
2. Open the GCode_Interpreter sketch in reprap-arduino-firmware-x.y/gcode/GCode_Interpreter/GCode_Interpreter.pde with the Arduino software.
3. Configure the firmware (see below)
4. Upload the sketch to your Arduino.
Step 1: Do I have to make a new folder under arduino-00xx/hardware/libraries for example arduino-00xx/hardware/libraries/reprap_new_firmware and put the files reprap_new_firmware.h, reprap_new_firmware.pde and ThermistorTable.h into it?
Step 2: Do I have to download the original interpreter and open the files from step2?
Maybe the answer should be posted in arduino-gcode-interpreter
