I'll show you how to calibrate the E-steps and flow rate for an Ender 3 or other FDM 3D printer. I investigate how flow rate actually affects the print's measurements and surface quality. Many people have been suggesting to calibrate flow rate using the single perimeter thickness method, but I found out that it isn't at all a good solution to the problem it's trying to fix. Calibrating E-steps is actually a good way to make the slicer's work more accurate for better printing quality.
