GCode Print Simulator
by mdietz, published
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.

Thanks for the feedback. Could you please send me such a BfB gcode, then I can check how to improve the behavior.
In fact, it should already try to move the 0 position based on the 3d object size, maybe there is a bug in this logic.
My printer is a Rapman from Bitsfrombytes and on these machines the coordinate (X0,Y0) is the middle of the printbed.
It seems that for GcodeSimulator this coordinate is at the bottom-left corner of the screen.
Therefore the simulation occurs in that corner and can't be completely seen.
It could be a good point to be able to tell the program where the origin is with some X and Y offset. Just an idea...
I also know that some Gcode for BfB machines might be different than for other machines.
So maybe it won't be able to completely simulate BfB gcode.
Anyway this seems to be a very great app !

Much smoother painting by splitting longer lines into multiple draws
Added nice looking labels with boxes for current infos (instead of plain test string)

Start the java program by calling on the command line (Java 1.6.x required)
java -jar GCodeSimulator.jar
Or Open with java from explorer or your favorite file browser.
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 !
