There must be some sort of GCode for the printer to start "printing the .cube3 in printer's memory" somehow...

I sometimes send the file via wifi just to click the wrong button on the cube and having to start the transfer again but im pretty sure the file is still there in the cube memory... i was playing the other day with the gap leveler tool while sending a file over wifi and somehow it briefly interrupted the gapping process with the "level your bed before printing" advice just to go back to the gap routine, reset back to point 0. So Im pretty sure the file remains in a temp folder and a Gcode just starts the "seek any file in that folder and print it!" routine hmmm
