Before Transforming the 3D Printer
Follow these steps to pull out the filament, or it will jam the nozzle next time you want to use it.
1) On the Touch Screen, go to Controls > Change Filament > Confirm.
2) Wait until the nozzle is heated to 200°C. Tap Next.
3) Press the button on the front of the 3D Printing Module, meanwhile, insert about 10 mm of the previous filament into the hole and then quickly pull it out. Release the button after the filament is pulled out.
