June 13: Avoid Printing Too Close to the Bed—It Crushes the First Layer

Introduction

What is the best 3D printer first-layer settings? A too-low nozzle can smash the first layer, causing poor adhesion, uneven extrusion, and difficulty removing prints from the bed. Proper Z-offset settings ensure better print stability.

Why This Matters

If the first layer is too squished, filament spreads unevenly, leading to adhesion issues and surface defects. Finding the right nozzle height ensures clean first-layer placement.

How to Apply This Tip

✅ Adjust Z-offset slightly upward to prevent excessive filament squish. ✅ Perform the paper test—a slight drag is ideal for a perfect first layer. ✅ Use auto-bed leveling but manually fine-tune for precise results.
