STLBEAST Calibration Lab Calibrate in dependency order—not by guesswork. A reliable profile starts with mechanics and first layer, then temperature, flow, pressure control, retraction and performance. Your progress is saved privately in this browser.

Safety and mechanical baseline Inspect cables, connectors, toolhead motion, fasteners, belts, wheels or rails, fans, build plate seating and obvious damage before tuning software.Firmware and machine identity Confirm the selected printer profile, build volume, nozzle size, kinematics and firmware expectations match the actual machine.Bed, plate and Z baseline Clean the plate, verify mounting, level or tram as required, run mesh calibration, and set a reliable Z offset.Extrusion path Dry filament when needed; inspect spool path, extruder grip, PTFE path, hotend, nozzle and cold-pull condition.Temperature Use a temperature test with normal cooling and representative speed; choose the lowest temperature that bonds cleanly.Flow / extrusion multiplier Run a controlled flow method and measure surfaces; do not use flow to hide a clog, wrong filament diameter or mechanical feed problem.Pressure advance / linear advance Tune only after temperature and flow are stable; use the firmware and slicer method appropriate to the printer.Retraction and travel Tune retraction only after moisture, temperature, nozzle condition and travel behavior are controlled.Speed and acceleration Increase performance gradually while checking ringing, skipped steps, cooling limits and volumetric flow.Bridges, overhangs and supports Tune cooling, bridge speed/flow, orientation, interface and support distance with small representative tests.Dimensional and functional fit Use designed fit coupons and repeated measurements; avoid blindly changing steps-per-mm based on a single small cube.Save and verify Run a representative model, record the complete profile, and preserve the known-good baseline before experimenting further.
Do not compensate for hardware faults Temperature, flow and retraction tuning cannot safely repair loose wiring, a damaged heater, unstable thermistor readings, a clogged nozzle or slipping mechanics.
Use the smallest meaningful test A test should isolate one variable and resemble the real feature you need to print. Record the result before changing the next variable.
