This application can visualize Gcodes and simulate a real 3D print.
GCode Simulator recognizes the print speeds and can simulate the print in realtime, but you can also speedup the prints (fast forward,slow motion). Each layer is painted in a different color to see how a layer overlaps with the layer below.

GCodeSimulator let you to check how your print should turn out, making it easier to spot errors and fix them instead of wasting filament. If the print object looks ok you can directly send it over Wifi to GCodePrintr (Android) to print it.
GCodePrintr - 3D Printing for ANDROID available
Allows real 3D printing from an Android device
In addition GCodeSimulator analyses the Gcode file and prints additional information like:
It calculates various print details like
-yx move distance
-print object dimension
-average print speeds
-number of layers
-speed distribution / Acceleration
-weight and price of the printed object
-much more ...
It also allows to debug your gcode by stepping through it line by line and show the results. (debug mode)
Developed for my reprap printer but works with other printers (e.g. makerbot, ultimaker,...) as well, tested with Silc3r and skeinforge gcodes.
Download the latest Version V134
Add GCode Simulator as post-processing script in Slic3r !!
Latest Update V1.34
Many improvements for CNC (non-3dprint) gcodes
Fixed gcode parsing issues
Calculate filament usage by extruder
How to start GCodeSimulator on Windows/Linux/MacOS
GCodeSimulator is written in Java and therefore requires a Java Runtime Environment (>=1.6) to be installed on the System. You can get the Java JRE from www.java.com (Oracle).
Once Java is installed you can start GCodeSimulator by double click on the GCodeSimulator.jar file. (Open with java from explorer or your favorite file browser.)
Do not extract the jar file ! (Windows explorer might show it as a tip archive)
If this does not work, please start GCodeSimulator by calling java from the command line
java -jar GCodeSimulator.jar [gcode_file]
[gcode_file] is optional , if not specified then a browse dialog will open.
IMPORTANT: Due to a bug in the linux java jre do not choose a file from the "recent file" list, this will cause a crash. Instead go to the full path of the file and open it there.
The GCode Print simulator can be controlled with the following hotkeys:
I have tested it with many Slic3r gcodes and some skeinforge gcodes. But GCodes can be very complex, therefore I'm pretty sure there will still be bugs.
Z-Lifts might causes problems and negative coordinates as well (fixed with V0.65). Relative positioning is not supported yet.
Feedback is highly welcome !

Added increase/decrease of speedup in larger steps (10x). Use / (Up) * (Down)
The current location of the nozzle is painted to improve usability.
Replaced blue with a lighter pink to improve readability.
Click on speedup label box will toggles pause
Scrollwheel for speedup is only active when mouse is over printbed or labels
