Notes

Hark Tech bench starting point for the Centauri Carbon in Orca. Calibrate per filament: flow ratio from 0.98, pressure advance usually 0.020–0.035 for PLA, max volumetric test (most PLA tops out around 22 mm³/s). Defaults: 3 walls, 15% gyroid. If it still strings, drop the nozzle 5 °C before adding retraction.
