    • Click add to open file picker window.

    • Our installer created a folder with 3D objects on your desktop, so double click it.

    • For our example choose Batman.stl and click open.

    • Batman is loaded in a 3D view!

    • Now click Export G-code to prepare the 3D model for printing.

    • Choose a filename and click save. Slic3r will work for a second.

    • If you click a Preview button on the bottom, Slic3r will switch to G-code 3D preview. In case the Preview is not working right away, check the Option File -> Preferences -> Background Processing is enabled. Otherwise, the Preview will not show any layers until you have exported G-code first.

    • Use the slider on the right to change layers.

    • Copy your .gcode file to your SD card and start printing ;-)

Hi Alaa and Danie,

I would recommend printing from the SD card. In the case of longer prints, the computer can go to sleep mode, freeze or the app can have a failure. SD card is more reliable.

Thr Retier Slicer3 tells how long the build will take. Have had to use the Pointerface software to get this information. Could you add this feature to next Slicer3 update?
