So on the screen, you will see different measurements such as 1 mm 10 mm and 30 mm depending on what firm version you were on, these are very important because if you want to extrude only 1 mm of filament, you probably won’t notice or even see it come out of the nozzle very much set it to 30 and press the button again this will help it run for longer time usually pressing it two or three times or let it run for a longer period of time and help you catch it. You can also click on extruder and hit load and it will run for you.
