Calibration Workflow
01
Mechanical Checks
Frame squaring, belt tension, axis motion verification
02
PID Tuning
Hotend and bed PID calibration via Klipper's built-in command
03
Extruder Calibration
E-step measurement and rotation_distance adjustment
04
Bed Mesh & Z-Offset
5×5 BLTouch mesh, probe calibration, first layer validation
05
Flow Rate
Single-wall cube measurement, extrusion multiplier adjustment
06
Temperature Tower
TUNING_TOWER from 195→220°C, 5°C steps every 5mm
07
Retraction
Distance and speed towers — optimized to 3.8mm @ 60mm/s
08
Pressure Advance
TUNING_TOWER from 0, factor 0.005/layer until corners sharpen
09
Input Shaping
ADXL345 resonance measurement on X and Y, CALIBRATE_SHAPER
10
Speed & Acceleration
Max accel capped at 2000 mm/s² — above this causes seam separation
