Calibration sequence0 of 12 completeSafety and mechanical baseline — inspect cables, connectors, motion, fasteners, belts, rails, fans and build plate seating.Firmware and machine identity — confirm printer, build volume, nozzle, kinematics and firmware expectations.Bed, plate and Z baseline — clean, tram or level, run mesh and set reliable Z offset.Extrusion path — inspect spool feed, extruder grip, PTFE path, hotend, nozzle and filament dryness.Temperature — choose the lowest stable temperature that bonds cleanly.Flow or extrusion multiplier — tune only after the feed path and temperature are stable.Pressure advance or linear advance — tune after flow, using the correct firmware method.Retraction and travel — tune only after moisture, temperature and nozzle condition are controlled.Speed and acceleration — increase gradually while checking ringing, skipped steps, cooling and flow.Bridges, overhangs and supports — tune with small representative tests.Dimensional and functional fit — use fit coupons after flow and first-layer corrections.Save and verify — run a representative model and preserve the known-good baseline.
Do not compensate for hardware faultsTemperature, flow and retraction cannot safely repair loose wiring, a damaged heater, unstable thermistor readings, a clogged nozzle or slipping mechanics.
Use the smallest meaningful testEach test should isolate one variable and resemble the real feature you need to print. Record the result before changing the next variable.
