1) Control Clamping Pressure
Ensure the clamping pressure is moderate when using chucks to grip the material. Excessive clamping can damage the material or deform the chuck, affecting the engraving process. On the other hand, if the grip is too loose, the material might shift or rotate unexpectedly, compromising engraving precision and quality. The grip should allow you to manually rotate the chuck while maintaining firm control over the material.
