IV. Reducing print speed ? why not
When you increase the temperature and speed up flow of the filament you will be able to print really fast. There is big BUT ! High speed printing is bringing a lot of problems which can occure. If you hear a clicking during printing this could be a sign that the printer is going to fast. That means filament is running faster in to the noozle than viscosity change of the filament. Reducing printing speed can help a lot. You can adjust this parameter in your slicer software or directly in printer settings. For more info please see user manual of your 3D printer.
