1. Test Printing & Real-Time Monitoring
- Calibrate nozzle-bed gap: Adjust to 1-2mm (via shims or software) for good first-layer adhesion.
Monitor during printing:
- First-layer adhesion: Ensure even spreading with no warping or air bubbles.
- Layer bonding: Check for tight connection between layers (no separation or collapse).
- Mechanical operation: Smooth axis movement, accurate nozzle positioning, no abnormal noise.
- Material supply: Continuous feeding—clear nozzle residue promptly if clogging occurs.
