1
⚙️
→
Extruder Steps / Rotation Distance
First calibration — how much your extruder actually extrudes per command. Every other calibration depends on this.
⏱ 5–10 minBeginner
2
🌡️
→
PID Tuning
Stabilize hotend and bed temperature. Run before temperature tower — unstable temp = invalid results.
⏱ 15–20 minBeginner
3
🔥
→
Temperature Tower
Find the optimal printing temperature for your specific filament spool. Affects layer bonding, stringing, and bridging.
⏱ 45–60 minBeginner
4
⚡
→
Max Volumetric Flow
Find your hotend's real speed limit in mm³/s. Defines your actual maximum print speed, not the slicer setting.
⏱ 30 minIntermediate

Pressure Advance
Eliminate corner bulging. Pattern method + Adaptive PA for Klipper ≥0.13. Works with Klipper, Marlin, Bambu.
⏱ 10–15 minIntermediate
6
💧
→
Flow Rate / EM
Fine-tune exact material deposition. OrcaSlicer Pass 1 + Pass 2. Correct EM is almost always below 1.00.
⏱ 10–15 minBeginner

→
Retraction
Calibrate retraction for Direct Drive or Bowden. Last calibration — depends on all previous steps.
⏱ 10–15 minBeginner
8
📏
→
Skew Correction
Fix rhombus-shaped parts. Calibrates XY, XZ, YZ axes independently. Klipper SKEW_PROFILE + Marlin.
⏱ 10–20 minIntermediate

→
Shrinkage Compensation
Compensate for material shrinkage with separate X and Y factors. Critical for functional and precision parts.
⏱ 10–20 minIntermediate
