Calibrating a New Printer from Scratch: The Complete Checklist

Danielle A.

The Full Calibration Stack

A new 3D printer, fresh from the box, is calibrated to generic specifications, designed to produce acceptable results for an average user. Getting from "acceptable" to "excellent" requires calibrating your specific machine, with your specific filament, in your specific environment. This checklist provides the complete, ordered sequence of calibration steps that transforms a generic out of box printer into a precisely tuned machine producing consistently excellent results.

Work through the steps in order, as each one builds on the previous. Don't skip steps or assume previous calibrations are correct without verification. Many printer operators spend hours troubleshooting print quality issues that they could resolve in minutes by working through this checklist systematically from step one. Use quality, consistent OzFDM PLA throughout the calibration sequence; filament inconsistency is one of the most common confounding factors in calibration work.

Phase 1: Mechanical Verification

1. Please ensure that all frame joints are square and tight.

• Measure diagonals on the frame; they should be equal within 1 mm. Adjust if not. 

2. Tighten all grub screws. 

• Tighten screws on pulleys, Z couplings, and shaft collars. A loose grub screw on a pulley or Z coupler is the most common source of mysterious print quality issues on new printers. 

3. Verify belt tension.

• X and Y belts should produce a consistent, low note when plucked. Unequal tension between X and Y causes dimensional accuracy issues.

4. Ensure the bed is mechanically clean. 

• Clean with IPA; verify the build surface is properly adhered and undamaged.

Phase 2: Electronic and Firmware Calibration

5. Calibrate e-steps / rotation distance

• See our extruder calibration guide. This is the mechanical foundation of all extrusion quality. 

6. Run PID autotune 

• For the hotend and bed, see our PID guide. Temperature stability underpins all subsequent calibration. 

7. Level the bed manually. 

• At print temperature, see our bed levelling guide. 

8. Run the ABL probe if equipped and verify the mesh. 

9. Calibrate Z-offset 

• For a live Z test print, please refer to our Z offset guide. 

10. Calibrate flow rate 

• With a single wall cube, see our flow rate guide.

Phase 3: Per-Filament Calibration

11. Run a temperature tower 

• For each new filament type, see our temperature guide.

 12. Tune retraction 

• At the calibrated temperature, please refer to our retraction guide. 

13. Calibrate pressure advance 

• For Klipper or linear advance (Marlin), see our PA guide. 

14. Please print a calibration cube and a Benchy, and refer to our test prints guide.

• Analyse results and address any remaining issues. Save the calibrated settings as a filament profile (see our profile guide). Your printer is now fully calibrated and ready for production use.
