I noticed using Marlin 1.1.9 that when I want to print from the SD card that hotend and bed start heating at the same moment.
I mention this because during the time the bed is reaching his temperature the hotend is burning the filament inside with as result that the filament path becomes obstructed with small parts.
Today I had to drilll-out the burned filament.
I am not a programmer but which statements must be changed to start first the heating of the bed and after that the hotend?
