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.

UPDATE V0.95 Version* Added guessed info about print material and diameter Added info about mass and weight (based on guessed material info) Added info about price (based on guessed material info + default price per kg=30€) Ability to specify environment variables to overwrite diameter and price per kg (FILAMENT_DIAMETER, FILAMENT_PRICE_KG) (Guessing of PLA or ABS is based on temperature, Diameter guessing based slicer comments or rough guess assuming WOT=~2) . Fixed some issues with Skeinforge comments and average calulations.

UPDATE V0.94 Version* Added support for Java 1.6 (MacOS)

UPDATE V0.93 Version* Fixed issues with Z-Lift and negative coordinates. Added "position on print bed" to model details. Show gcode load time and analyse time. Added undodumented option "g" for debugging (print gcode details)

Start the java program by calling on the command line (Java 1.7.x required) java -jar GCodeInfo.jar [mplnscg] gcode_file
