This was created for my mobile systems exam at university of applied science in Lemgo, Germany.

This app can visualize GCode (created with Slic3r) for RepRap and Makerbot 3D printers.

It can also color code the Gcode when you enable the verbose Gcode in Slic3r.

Update (06.02.2013):
I now have a Lenovo IdeaTab with Android 4.0.3. I tried my GCodeViewer and the app crashes all the time. I will try to update the app to work with more devices. I hope I find some time between my exams and my bachelor thesis to work on this project again. :)

Download the App and install it on your Android phone.

You can find the latest version here:

Still need to rework the 3D Visualization but my Bachelor Thesis is consuming most of my free time at the moment.

Android 2.2 or newer is required.

The app works on:
Samsung Galaxy GT551
HTC Desire Z
HTC Evo 4G and Cyanogen 7.2

The 3D visualization works not on:
Motorola Milestone
Samsung Galaxy S2

This is maybe because of OpenGL ES 1.1 or its something with GL_LINE_STRIP.

I will publish the source code as soon as I have the results of my exam.
