I created an embossed image of my wife from a 2d photograph, added a support plate and grouped them. Then saved as a .stl file and converted to .gcode in Cura. Put the file on the sd card and tried to print it. The progress bar moves rather fast, but nothing else happens. All the steppers don't move. Only the progress bar goes to the end and stops like there has been a printed object, but nothing is printed.
I don't understand what I do wrong. Please help... very much appreciated.
