Speed and temperature can already be changed during print, flow rate Some 3D printing wizards believe in using the Flow Rate adjustment as a last-ditch solution. The default value for the flow rate is usually 100%. Using these settings, the 3D printer figures out how fast to run the extruder motors to send enough filament for printing through the hotend. How to Run it: The flow rate is denoted by the Flow Ratio in OrcaSlicer. In addition to understanding how to calibrate 3D printer, you should also pay a little attention to the 3D printer itself. Use this calculator correct for the expansion of the filament by adjusting the flow rate. Every hotend and extruder combination has a capacity to melt and deposit a certain volume of filament every second. Calibrating your flow rate (extrusion multiplier) will ensure you are getting the optimal volumetric flow from your hot end. In this video I'm going to quickly show you how to calibrate flow rate for your 3d printer using Cura. While accelerations and speed of the printer can be increased, a wall will be hit if the hot-end system is not capable of pushing enough plastic through the nozzle. For a regular filament, you usually won't need to perform a Flow Rate Calibration. It determines how fast and efficiently your printer can operate. Simply put, every movement-related parameter, such as travel speed and print speed, is multiplied by the feed rate value, and the resulting values are taken into effect by the printer.
