Pressure Advance Calibration
Pressure advance (linear advance) pre-compensates the elastic pressure that builds in the melt zone, so extrusion stops swelling corners and starving line starts as speed changes. It is tuned per filament with a pattern or tower test; PETG's springy melt usually needs a higher value than PLA on the same machine.
