GCodePrintr enables you to use any Android tablet or phone as a touch screen for your 3D printer and to run 3D prints without the need for having a PC running. With the intuitive UI interface you can always see what the print status is (e.g. remaining time) and modify print parameters (speed, temperature, etc.) during the print. Your Android device can also act as a web server to allow you to start a print remotely or watch the print status.
IMPORTANT: Before buying this version make sure that your printer connection works with the free version: GCode Simulator (Free).

See 3dprintapps.de for more information.

★ Visualization and Simulation
GCodePrintr can visualize gcodes and simulate a 3D print. It recognizes the print speeds and simulates the print in real time, but can also speedup the simulation(fast forward).
Each layer is painted in a different color to see how a layer overlaps with the layer below.
✔ Layer by layer visualization and simulation
✔ 3D View
✔ Show estimated print time
✔ Show remaining print time
✔ Show weight and cost of the printed object
✔ Show speed of X/Y/Z movements and extrusion (min/max/average)
✔ Show Print object dimension and required filament
✔ Show details of each layer
✔ Multiple UI Themes
and more


⚠ Remarks and Limitations
Printer connection requires a Android device with USB-OTG support and a USB-OTG adapter.
Tested with Slic3r, Simplify3d and Skeinforge generated gcodes.
To load files locally from the device or dropbox you need to install a Android file manager (e.g. ES File Explorer)
MakerBot uses a proprietary protocol called S3G where as others use raw G-Code, therefore only the gcode simulation is supported.
Loading very large gcode files might fail, depending on the available memory of the device. OctoPrint support is experimental.
Tip:Use GCodeSimulator for PC to send files from PC directly to your Android tablet to print them.
