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?
