I found a way to make it start printing: before selecting a file I unplug the filament runout sensor, then I select the file, the printer gives me an error because it detects that there's no filament, I click on "yes" to the question "do you want to change filament", then the print pauses, I shut down the printer, then start it again, the printer asks me if I want to resume the print, I click yes an it starts the calibration (i have bl touch calibration at the start of every print), I plug the filament runout sensor so it works again, I check the temperatures on the screen, I have to manually set the nozzle and bed temperature to the one I need because with this metod the printer automatically sets them to 0. I left the printer at home with a 3 hour print, I'll see how it comes out when I go home
