Anycubic Kobra S1 Z offset optimization First Layer Test

This profile is designed specifically for precise first layer calibration and Z-offset tuning using a minimal amount of filament (~4.8g). It provides a structured test pattern that allows users to visually and analytically evaluate bed adhesion, extrusion consistency, and nozzle height across the entire build plate. 🔍 What This Profile Helps You Diagnose First layer adhesion issues (corner lifting, patch inconsistency) Z-offset accuracy (too high = gaps, too low = over-squish) Bed leveling uniformity across all regions (Front, Back, Left, Right, Center) Extrusion consistency and line merging behavior ⚙️ Key Features Low material usage (~4.8g) → cost-efficient calibration Full-bed coverage pattern → tests all critical zones Segmented square + line grid design → clear visual feedback Fast print time → quick iteration cycles Compatible with PLA, PETG, ABS, ASA 📊 How to Analyze the Print Perfect layer → smooth, slightly squished lines with no gaps Too high Z-offset → visible gaps, weak adhesion Too low Z-offset → rough surface, over-extrusion, elephant skin effect Uneven bed → variation between different zones (corners vs center) 🚀 Ideal For New printer setup After nozzle/bed changes Switching materials Fine-tuning for high-precision prints (like flexi toys, functional parts) 💡 Pro Tip Run this test while adjusting Z-offset live during printing for best results. Once dialed in, save your tuned profile to avoid re-calibration.
