Print Quality & Calibration Guide

Flow dynamics (pressure advance) calibration

Run this per-filament, especially after switching brand or color of the same material — it tunes how far ahead the printer starts slowing extrusion before a direction change, directly affecting corner quality.

Vibration compensation

Measures frame resonance and adjusts acceleration to avoid it, keeping ghosting/ringing (see the Print Defect Visual Glossary) low. Re-run after moving the printer.

First-layer inspection

Without the X1 Carbon's LiDAR, the P1S relies more on the camera-based monitoring and your own eyes for first-layer checks — it's worth watching the first layer yourself when trying a new material or spool.

When to recalibrate

• After changing nozzle diameter
• After moving the printer
• If a specific filament suddenly strings or under-extrudes despite no recipe changes
• Periodically, every couple hundred hours

Tip: If quality issues are isolated to one AMS slot's material rather than the printer overall, the problem is more likely that spool than a calibration issue — see AMS Filament Jams & Loading Failures.
