GCodeInfo

This is a small command line tool to analyse gcodes (control codes for 3D printers, CNC,...). It calculates various print details like:

• print time -used filament
• yx move distance
• print object dimension
• average print speeds
• number of layers
• layer details
• speed distribution
• weight and price of the printed object ...

I used it to optimize my slicer settings and print times for my reprap printer. Tested mostly with slic3r generated gcodes.

Building

Prior to build the project, you will need:

• Eclipse IDE

Once installed:

1. Clone or download (And decompress) this repository to your computer

2. Open the GCodeInfo folder as a project in Eclipse

3. By default, projects will build automatically but you can prevent this by clicking on the Project menu and unchecking the Build Automatically button. Then, every time you want to build the project you will need to click the Project > Build menu

4. You can build a .jar file inside of the build directory by right-clicking on any of the .jardesc files and then on the Create JAR context menu. The project contains two .jardesc files:

   • GCodeInfo_generated.jardesc: Will create a .jar file only including the compiled files and the resources of the project.
   • GCodeInfo_all.jardesc: Will create a .jar file containing all of the project files, including the compiled and the source code files.

   By default a .jar file is available on the build folder of this repository to use it without having to compile the project.

Usage

Start the java program by calling on the command line (Java 1.7.x required)

java -jar ./GCodeInfo/GCodeInfo/build/GCodeInfo.jar [mplnscg] <GCODE_FILE>

where <GCODE_FILE> should be replaced by the path to the G-Code file you want information about.

The software will work with default values for the filament diameter, filament material and filament price per Kg settings, but these defaults can be overriden with the use of environment variables which in bash can be set as follows:

export FILAMENT_DIAMETER=1.75
export FILAMENT_MATERIAL='PLA'
export FILAMENT_PRICE_KG=30
java -jar ./GCodeInfo/GCodeInfo/build/GCodeInfo.jar [mplnscg] <GCODE_FILE>

Instead of calling java -jar ... directly a bash script is included inside of the GCodeInfo/build folder so that in Linux and macOS you can call it as follows:

./GCodeInfo/GCodeInfo/build/GCodeInfo [mplnscg] <GCODE_FILE>

this script can be symlinked and executed without issues as long as the .jar file is kept on the same folder as the script

Output Example

GcodeUtil 0.91
Usage: GcodeUtil [mode m|p|n] gcodefile [
Modes:
m = Show Model Info
l = Show Layer Summary
p = Show Printed Layer Detail Info
n = Show Non-Printed Layer Detail Info
s = Show Printing Speed Details Info
c = Show embedded comments (e.g. from slicer)
Example:
Show Model Info and Printed Layers
GcodeUtil mp /tmp/object.gcode
Show All Info
GcodeUtil mlpnsc /tmp/object.gcode
