While printing, you are able to control the print speed and extrusion rate of your print using the Tuning Adjustment in the Control settings panel. It is based on a percentage of your printing speeds with 1 being 100% of your print speed. Eg. If you are printing at 50 mm/sec and you increase your Speed Multiplier to 1.2, you are now printing at 60 mm/sec. Extrusion Multiplier is used to increase or decrease the amount of material deposited per unit of distance travelled. A lower number here will allow for integrated hinges and tight tolerance parts to move or fit easily.
